User Reviews

Was using Unison, but there weren't many updates and it doesn't support x64. FreeFileSync is very simple to use! Also it is much faster than Unison! I recommend it!

— geek-man

I got a similar app from PC Magazine a few years ago. I never really figured out how to use it. I tried to start it up and it would not load for reasons unknown. I googled just in case I might stumble across... THIS! It did precisely what I wanted to do. I figured out how to operate it pretty darned quick, which is a testament as I'm gettin' old and am not as fast on the uptake as I once was.

— chinnboy m.

It has become my preferred sync and backup program meanwhile. Keep on developing and improving!

— Frank Nitsche

After successful tests, i permanently installed the program with 6 TB of data exchanged between 2 x 3 hard disks (12 TB total) and it since works reliable and fast. It's even better than the best commercially available software, so there goes a big THANK YOU to the fantastic programmers and the GNU open source community & last but not least to sourceforge!!

— weathercontrol

I've been using this utility for more than a year now and still recommend it!

— Caspar Schutte

Favourite tool I have used. Thanks so much. Makes keeping my USB stick and google drive in perfect sync.

— DG

Have used this in the past to great satisfaction. Just came back, because ... well, you just have to have this. Way outperforms anything you can do manually and better than any other tools I've seen so far.

— Jan Derk Otter

Works perfectly on Mac!!! :-)

— Pe Klak

Before I knew about FreeFileSync I used SyncToy, but FreeFileSync is better and quicker. Thanks

— Hartmut Boesch

Thanks for this wonderful sync tool that simply works where many others fail miserably!

— Harrer Christian

I have worked with Vice Versa and FreeFileSync. There is no comparison. FreeFileSync is one of finest and most important applications ever written. It works perfectly and handles a critically important computer task that too few people do. Vice Versa had at least one fatal flaw that was insurmountable: If folders had to be created on the destination side, they were created in all lower-case, regardless of the case of the source side. Consequently, the subsequent compare always failed. Their tech support was supposedly unaware of the problem, could not resolve it, and eventually avoided further contact. FreeFileSync is as good as it gets.

— George ALEFantes

Incredibly useful, manages long path names better than anything else we tried including Robocopy.

— robbo7877

I gave up on MS SyncToy — it wasn't deleting files and folders properly when mirroring and was creating duplicate copies of overwritten files. FreeFileSync works perfectly and is easy to use. Absolutely first-rate software!

— Robert Bunnett

Awesome software, very useful! And one of the few software titles compatible with Linux < Thank you from France for your work!

— Florian Mougin-Martelet

This program already helped me a lot, and I am not even using it to its full potential. I like how 'close to the user' the interaction with the files is. At every point in time I know exactly what the program does. When it comes to the safety of my files, this is how I want it to be. Thank you very much!

— Adrian Stroschke

I have been using FreeFileSync for the last one year and have been a very happy user. It is easy to install and very easy to configure and use. I would recommend FreeFileSync usage.

— Mahinder Nath

I've been using FreeFileSync for two years and it is great. I donated through PayPal :-)

— Umberto

With around 2 million files to compare/mirror, a lot of other tools run into problems with memory, long paths or performance (especially 32-bit tools, when the memory needed to represent the internal file lists exceeds the 2GB process memory limit).

FreeFileSync not only uses a lot less memory for large numbers of files but also provides a native 64bit build, eliminating any possible memory problems with large numbers of files (unless you run out of physical memory).

It also supports long paths, does the file listing in multiple threads (one thread per drive AFAIK) and has just the right amount of configuration options needed to achieve everything without bloating the UI with too many options.

Just started using it today, but I'm really impressed already.

— Christian Vogel

Excellent, works like a charm. I was long looking for something like that to keep two large HD identical.

— Olivier Lengwiler

Absolute best. I wish I could point to some issues but I can not think of any major flaws. One minor is that there is no ability to choose the installation language and so it forces an auto-detected language but that is all. Great app.

— infinum

FreeFileSync is 99% perfect. I love it. I cannot tell you how much benefit I am getting from it and how much labor it is saving me. The user interface is superbly designed and the functionality is terrific.

— James Gordon

Well done! I love this software. This is the best software for synchronization. Thank you.

— Cong Thinh Bui

Fantastic product. I've been using it for a few months now and files between two computers are syncing perfectly.

— Andrea Hatley

One of the most useful utility programs that I have come across and which I use repeatedly!

— Alex Burjan

FreeFileSync is truly a fantastic program and it is portable too. I have installed it on an USB stick. I had been using Syncback for over 5 years. I found that FreeFileSync is the only open source freeware that can match the paid version of Syncback software in terms of speed in handling folders with huge number of files (up to 30Gb). It runs perfectly in Windows XP SP2. Its web site says FreeFileSync can run in Linux as well. Many thanks to the author Mr. Zenju. I am sure this software will in time become an extremely popular download.

— Winson Cheung

Congratulations on knowing what OneDrive is which is more than one of your competitors knew and is why I am here.

— Bruce Gaugler

Part 1/5

Excellent software! I love it!

— Link Liu

Surely the best sync application currently including paid ones. Simply the best and works flawlessly. Meets the requirements of people who have to work on multiple systems.

— Uday Krishna

Maybe one of best synchronizing tools! I know some others too! But this one did exceed my expectations!

— Gerhard O.

Very useful software when using more than 1 computer — also effective for file transfer between Mac and Windows

— Callum McDonald

An excellent program with several unique features of its own. Can handle some stuff that even some fully commercial products can't.
Zenju is very responsive to queries, active in the help forums and always striving to make it better. What more can we ask? I like it so much I've hit up Paypal and sent him some cash. Well worth it.

— smeghead77

Great stuff. Competitor was AllwaySync, lost due to missing FTPS. Yours could be even nicer if it included a scheduler or a mechanism to inject the scheduled task automatically into the platform scheduler. Thanks for the work.

— Martin Baur

You make a great job saving my data!!! In a very comfortable way — running better than every sync software I ever had!! Thank you very much!!

— Tobias Möller-Hahlbrock

We use this app in our 2-man team to keep Dropbox and several PCs in sync. No issues whatsoever. Highly recommend.

— Vlad

One of the best utilities I've used in over 20 years of using Windows systems. Simple and easy to set up and use. THANKS!!!

— Edward Perez

Thank you for this amazing software, been searching for it for a while as a solution for syncing games in a LAN Gaming Center without resorting to a Gaming Cache Server. Your solution is much better when implemented properly.

— Mahmoud Shatila

One of the best sync programs I've found for Windows and Ubuntu. This software has a streamlined interface that allows access to the most frequently used features quickly. But also allows many advanced tweaks like what to do with deleted files etc. The program is fully featured yet not bloated. I've used it for about 3 years and really haven't found anything else this well written. Keep up the good work! Love it!

— wchang778

I'm glad I found this program! Helps me a lot to back up my media files to multiple external hard drives. I was going to make a script but this is much more useful.

— Jasper Riku Antero Lehikoinen

Hello Zenju, this app is the only app that syncs files correctly on a Mac. GoodSync and other apps can't find changes when the files are deleted. And only your app can delete into Mac's Trash folder! 5 Stars! Big thanks for developing FreeFileSync!

— Christian Schmachtenberger

This has become my favorite file synchronization tool. Even Araxis Merge seems to have lost its appeal. FreeFileSync uses some special undocumented APIs to accelerate folder reads, and it shows! Also, with the ability to use 3rd-party tools like WinMerge or RapidCRC to compare at a click, it's pretty simple to view changes before committing.

— Ascend4nt

This software is so cool that I like it very much, it just feels as convenient as SVN or Git. Thanks to your team of developers.

— 徐鑫

This is the most useful tool and about the best free software I've come across in a long while.

— John Craig

The most amazing and useful piece of software I have. Particularly the versioning feature, which allows me to perform my backups with file history in a more useful manner than general backup software. It works well and is well designed.

— nw0002

Love the FreeFileSync software! It has made backing up everything super easy and convenient for me!

— Scott Todd

Thanks for keeping it ad free! Love this software and couldn't do my backups without it!

— Palka Lukasz Kazimierz

GREAT work guys! I'm counting on you for my personal syncing among my backup drives. Thanks!

— Alejandro Ayerza

I love this program. It's the best file syncher out there and the fact it is open source makes it better. Now with a x64 version it is superior to anything else out there.

— wolssiloa

I use FreeFileSync and RealTimeSync to back up my files on my NAS and synchronize it automatically on several computers running on Linux and Windows. This is a great and efficient tool. Many thanks.

— Daniel Lathuilière

FreeFileSync is a mature and robust application. After using it for years on a daily basis I never had problems with losing data. An amazing feature of FFS that is difficult to find in similar applications is the ability to synchronize open files on network drives.

— Marcio Tibirica

I've been using this tool for a while now and it's simply awesome. Former SyncToy user. Best way to keep a Dropbox style of sync with my external drives. I also dig the new look. Very stylish.

— OpenID User

Part 2/5

Far better than other sync tools for my needs. I was looking for something to backup new and updated games from my Steam library (over 200GB) to an external drive so I can uninstall games to free up space and not have to waste bandwidth re-downloading if I want to play them again.

With FreeFileSync, the scan/comparison results are presented well with lots of statistics, there are buttons to filter the results view with a single click, and I can exclude folders in the right-click context menu (sub-folders are not expanded automatically). The interface is kept simple by having certain elements context-based - buttons that don't have any use to your current task/step in the sync process are hidden. I accomplished what I was trying to do quickly and didn't need to refer to the help file.

The previous sync tools I had negative experiences with were DirSync Pro (too complicated) and Microsoft SyncToy (not complicated enough to be useful).

— TakeNapEveryday

The best of all I tried (Synctoy, Robocopy, etc.) for backing up 50 laptops to a server. Simple config, nice features: versioning, omitting select folders (like /AppData), daily logs for checking health. Easily automated using Windows Task Scheduler. Support is excellent, better than I've ever seen from anyone!

— David C. Menges

I have used a lot of sync tools. I am sure FreeFileSync is one of the best tools available in the market out there. Above all it is free!! Thanks a lot to the dev team for contributing such a wonderful product.

— oid-3474008

I love this application. It is simple to setup and use and extremely useful. Have used it for moving files server to server, backing up my documents, and even keeping my ISO directory in multiple places.

— Jethro

I have been using this for years. Fast and reliable, has saved me from losing work a few times. Love it!

— Robert Olsen

For the longest time I was looking for a simple straightforward synchronization program to make weekly backups. Finally I found it. Thank you guys for making this sublime program available for free.

— ،ثثس

Awesome product! Can't wait to utilize all the great features in the free software. Thanks!!!

— Patrick Monette

The best of the best...

— marvindl

Awesome application. Really fast performance, and it works exactly as you would expect.

— Alfonso Ruiz Martínez

I don't use this very often but it is what I need when I need it :-) Thank you for making this utility available.

— Linda Greene

Just started using FFS: Majestic software for backup. I promise to donate after a few months of use. I was using Microsoft SyncToy which MS never tried to improve. Kudos FFS Team.

— Harikumar

Excellent Program. A HUGE improvement over Sync Toy that I've been using for years. Anyone who wants to sync or backup should download and use this program. Many thanks to the developers

— deibiddo

Great! I've been searching for this kind of program for ages. Bonus would be keeping a backup of mail and browser data (Thunderbird and Firefox to keep it in the open source family) — which is two key items difficult to auto store in customized archives.

— Lars-Roger Moe

Solid as a rock. Previously only DSynchronise was close in terms of reliability (having tried a whole load of free and paid-for software). Super easy to use and runs flawlessly. The one thing I would wish for is the ability to automate running various configuration profiles or batch files. I,ve done so by creating a .bat file to run all the batches and can't really complain. Thanks to the author for this little gem.

— Aiadi

Keep up the great work. Your solution keeps helping me to organize my data across several computers in an intuitive fashion. It is stable, doesn't crash and does a rock solid job.

— Frank Sattler

This has to be the most useful free tool ever released. I'm a network administrator and when moving file servers, this tool outperformed Robocopy, Symantec, and many many others.

— ray

Thank you for this little tool! It's like SumatraPDF and 7zip, you make every day at the office a useful day!

— Moritz Müller

Great piece of software which I use from time to time without any problems. I don't know how good customer support is because I've never needed it!! Thank you :)

— Carol Kurian

This is best file transfer software ever. I have three backups and one button helps me keep them all synced.

— Khan Shahzada Haleem

This is one of the few programs I would actually be happy to pay for, as the updates are often, the author is awesome, the pictures of animals in the installer are super awesome, and it actually works as advertised.

— Colin Smith

Best tool for folder synchronization. Thank you for your work.

— GK

Really love this program and have been using it under Windows a lot. Now have an iMac and was really missing this program, so I am very happy to see that there is now also a MAC version. Thank you very much.

— oskar101

Phenomenal job! As a fellow software developer, I appreciate your hard work and wish you all the best.

— Mark Franchi

Tried half a dozen packages till I found yours. Wish I'd found it first — does everything I need.

— Ian Abbott

Thanks you for this great program. I'm using it to back up/sync my laptop/desktop systems via FTP. It's fast to the point and reliable. Once again thanks for all y’all do.

— Chris Fox

It works very well. I sync a whole folder located on my note, including a local * .pst from outlook to flash drive.

— Leonardo Dias

Exactly what I was looking for! Nice program, easy to use interface, works like a breeze!

— Edo Hulsebos

This is a brilliant piece of software. It is simple to set up and easy to use. I have been using it for a few months now and it has never crashed. I use it to sync to my Dropbox via BoxCryptor encryption. I don't completely trust auto syncing software, so this is a great alternative. It allows you to keep your original files on your computer, and also save separate back up files on your external drive or Dropbox etc. Well done guys!

— rogerturner2

Part 3/5

Works beautifully in multi-platform (Ubuntu Linux, Windows, Mac) environments.

— Auke

Kick ass on both Linux and Windows: definitely a top-100 open source project! Much appreciation to the developer for this great app! :)

— jmj288

I have found it to be the best file sync software I have used, of the many I've tried to date.

— Wilbert Janson

Much better than Microsoft Briefcase to which I held on for much too long. Thanks for your work.

— Annette Maier

Best tool for sync, we can use it on our server for folder backup.

— Surya Prakash Joshi

This program is excellent. I have been using it between 2 computers for 3 weeks and no issues. I was using SyncToy for a few years with few problems, but recently SyncToy began to delete the newer files, some of which I spent hours writing. Thankfully I found FreeFileSync and it is working perfectly.

— oid-3857101

Just wanted to say that I'm DEEPLY Grateful to you, for creating a truly AMAZING program, and for keeping FreeFileSync always on top of its game with the frequent and substantial updates you do on it! I don't know much about coding, but what you do my friend — I consider to be OUTSTANDING work of great quality. I'm not religious, but may you be blessed sir!

— Daniel Peev

Saved my life in the most critical times... Recommended to everyone.

— Excellent

Just had to say that FreeFileSync is really great. It's like the best and simplest out of all sync programs and I have tried quite a few, including famous ones. Thank you very much for your time and effort creating this software for the common good. ^ _ ^ I hope you live a long and happy life.

— Samuel K.

Hi there. I just have finally migrated away from Windows permanently and this program has been my life-saving replacement for TreeComp. It is actually better and quicker, and an absolute gem to use. You are a genius, thank you so much.

— Tim Clayton

Excellent program! Very intuitive and streamlined operation. Has all the file synchronization features I need and then some.

— Nico Gotin

One of the best software programs I've used and I've used a lot in the past 40 years.

— James Gord

Great application. A must-use for any file management solution, super rich and easy to use.

— Spaz

Thanx a lot for your excellent work. FreeFileSync helped me a lot in the past and will help me a lot in the future.

— Peter Schmidt

Thank you very much for keeping FreeFileSync up and constantly improving it for nearly 10 years! I am using your great piece of software since version 3 and never had any issues with it. Moreover, it's by far the fastest and most easy to use tool for backup & synchronization jobs! I highly appreciate the open source character and the powerful batch capabilities as this allows me to install the software free of charge on all PCs of my acquaintances (mostly elderly people with not much knowledge about computers) where I do the maintenance and support.

— Andreas Hüller

This has been my goto file sync tool for years. It's an A+ piece of software!

— Jeff Reed

The very best (and free) software for mirroring and syncing. I appreciate the fact it works on all major platforms, including Windows, Mac, and Linux.

— Brian Bunnell

The best file backup and sync software I have used for far. It's quick and easy to use. Please keep this software portable as that is one of its greatest assets. I use it to synchronize between multiple computers, drives, and operating systems seamlessly. Having a dual OS has never been easier. Thank you!

— wabassoap

Been only using FFS for a couple of days, but I already think it's pretty amazing. I'm happy to see the archive has frequent release updates. Keep up the good work!

— Shai Ben-Naphtali

I've been using FreeFileSync for years and I have to say thanks again for the great software, frequent updates and excellent support you give to us. Keep doing that!

— Tarcisio Alves de Menezes

I have dabbled with this tool for a couple of years. Time to get serious, and FFS has proven itself worthy of a production environment.

— Jack Riggen

Thank you for this great piece of software that is very useful and provides exactly the features that are needed!

— Thomas Stephan

I haven't even downloaded it yet but so far everything about your website gives me total confidence that I am about to get some really beautifully executed software! Great 'Vision' statement; FAQ is marvelously thorough!; intro demo video (ditch the music!); the feature list (wow!!); manual looks wonderfully comprehensive yet clear; very little not to love, so far!

— Carl Spagnoli

Works like a charm to sync my laptop with my external disk and my home NAS. I will not use anything else!

— Sundesh

FreeFileSync has replaced my data backup software (Acronis) with the feature "file-versioning". It allows you to keep a current full backup whilst archiving any changes/deletions. This feature can't be emphasised enough and is more useful than most backup software that starts with a full version and then keeps incremental or differential archive formats. FreeFileSync can run as a batch file and use VSS.

— nw0001

Very reliable application. It has everything you need for local files synchronization. I'm looking forward for Google Drive and FTP support.

— Elvedin Hamzagic

This is top-notch software, so glad it doesn't require the slow bloated .NET Framework! I love to support high quality independent software development. Keep up the great work!

— Josh Straub

Great app and very useful tool. Bug-free. Intuitive. Has everything you can imagine for file synchronization. Copy. Backup. Compare...

— Elvedin

FreeFileSync is pretty awesome. It keeps my two laptops and external backup drives in sync. User friendly with self-explanatory buttons. Extremely fast synchronization. Keep up the amazing work in updating this software.

— Dr.Janaka Vithanage

One of the best pieces of software that I know anyway. Keep up the good work for this a top-notch sync tool!

— H Kooistra

Saved my life. Now it takes me 30 sec instead of 45 min to update my 8000 files / 4 GB on LAN. I learned it in 30 sec. Simple and reliable.

— doru001

This is a really well done piece of software. The GUI is intuitive. It is fast. The file transfers are fast. I am really impressed with this tool.

— jashale

Fast, easy and reliable. A great tool to keep two (or more) folders synchronized (even when changes have been done on both sides since the last synchronization). Excluding certain files or folders from synchronizing is quick and painless.

The application will warn you when too much has changed in the folder contents since the last sync. It supports batch jobs. I personally use this software to backup my personal files onto an external hard drive. It works great through my home network too. Without a doubt, I prefer FreeFileSync over Synctoy and SyncBack. Thank goodness for FreeFileSync!

— zenphic

Part 4/5

I love the simplicity of this. Other programs compress and bundle which is unnecessary and obfuscating. This program is actually easier and simpler than copying folders by hand, because once you've set up your paths and saved them in profiles, you just choose the profile. If you put a little effort in at the beginning working out what needs to be backed up, then the existence of the profile in the list reminds you that you need to do a backup of it.

— andycivil

To me, the best file sync tool! No bugs, everything is clear, constant updates. And very simple to use.

— Joao Parrinha

I am doing frequent data transfers and have recommended this product to others. I have used ycopy in the past and this is in the same vain, but on steroids. Thank you.

— Morgan Barlas

This tool is a really nice application. I've tried countless sync tools, both free and paid. This is the one I've chosen to use. It works great in both Windows and Linux. Many many thanks to the developer(s). I know how much time and energy it takes to code and maintain something like this. I appreciate it. Keep up the great work.

— dtshudy

The best sync tool I have ever tried. Thank you for your devotion to constantly improving the software. Please go on.

— Petr Kabele

I just love this tool! Works great. Thank you for this project and keep up the good work! Best regards.

— Pia Gross

Beyond being a great piece of software, FFS has saved my butt a couple of times! Thanks!

— Cary Collett

Very intuitive, and because of its flexibility it's possible to have portable backups since it can backup to a relative file path. Then you won't need to change destination path when you move the backup folder.

— estogram

A GREAT piece of software that rivals other expensive software. Very versatile and always expanding. The developer is very helpful and responsive. Couldn't live without FreeFileSync!

— srjones67

Very cool. Now it helps me to keep folders in sync and backup files from internal and external hard discs, mp3 player and my phone... :-) Many thanks to the developers.

— magickz

Awesome. Much more versatile than SyncToy. I love the fine-grained control and also the option to preserve deletions. I use it on a couple of identical external HDDs for off-site backups. Different drive letters? No problem, just copy the XML config file and change the drive letter. Save. Run. Done.

— cadbloke

'Think Before You Sync'! FreeFileSync is so versatile I can't believe I ever had to live without it.

— Michael Papo

A wonderful tool! Peerless! Tons of thanks to its maker...

— bunnybat

I love this program, because it helps me to work in the train, in the kitchen, in the garden ... and I always have all my documents with me!

— Monica Schwarz

Hello, I chose your software because it was the only one I found that syncs my music from PC to Android phone. It's seriously well-made, including tutorials. Vision is pretty nice and clear too! So, thank you.

— Bernard Rene

What a simple yet incredibly helpful and powerful program! The user interface is flexible enough to house lots of things or to be very simple and sleek - and it performs binary comparisons! Cheers for a job well done!

— jeffplemons

I am using it since ... I don't remember. Easy, reliable, good. I recommend to anyone.

— Tomasz Stankiewicz

Thank you for this software! It is brilliant to have such an easy to use reliable sync tool. It makes doing data backups quick and painless. Being free was a real surprise!

— Robert Coleman

I use FFS more often, and like it better, than Beyond Compare or Exam Diff. Thanks for your excellent program.

— Harold Bradtke

Thanks for the continued AWESOME software :-) I have this for both personal and professional use!

— Robert Smithlin

From my experience until now, it is a great and simple backup software. Great performance, analysis, scan, progress bar and graph, great comparison, flexible so you can configure multiple folders and multiple actions. Nice UI. Does the job as it should.

— liran1

I've been looking for a tool like this for about 3 years, when my most favorite directory sync tool stopped development, short of Windows XP. GREAT work on this. Clean, efficient, simple dir comparison or sync. Run it and it shows you what's out of sync, without all of the complicated configurations, etc. that other dir sync tools have. Thanks.

— rgadawg

Fastest and easiest and most trustworthy sync program I've ever used! Been using for years. There is nothing quite like it! Also great that it is customizable!

— Bert Branson

This is the sync program that I will work with from now on. I am very grateful for its existence.

— Jim Brook

After wasting $40+ dollars on a competitor's product, I tried out freefilesync. FreefileSync was able to compare hundreds of thousands of files (NAS->NAS) in 10 minutes, which was taking the competitor's product over 3 hours. I ended up deleting the competitor's product and relying on FreeFileSync. Awesome, awesome backup program.

— lechuan

I have been using FreeFileSync for YEARS!! It's an amazingly helpful tool! Thank you for all your work on it.

— Nathan lacroix

I have just discovered your wonderful FreeFileSync software. For years I've been using ViceVersa which runs on Windows. Now I have moved everything to Linux, and searched for a ViceVersa replacement in vain. But the discovery of FreeFileSync changed everything. It's BETTER than ViceVersa!! Out goes ViceVersa and I have yet another native Linux app.

— John G.

Very good software utility at the unbeatable price of free?! Thank you so much for building this piece of software.

— Derek Matteson

Excellent, works perfectly between my MAC and my corporate server based on a Microsoft environment. The only "bad" point that I see, is the usage of Realtimesync, a tool to automatize the synchronization when a folder becomes available. It's not fully explained how to manage more than one directory!

— amaygeoz

Excellent, efficient tool for manual backup and folder mirroring. No persistent services. Does what it promises and is updated frequently. Takes advantage of multicore now. A big thanks to the developers.

— godlymusic

Simple, usable without a large manual, fast, totally free trial, no BS. Please keep showing the big moguls how it should be done.

— Hendrik Kok

No ads, and free with seemingly all the functionality of programs that cost 60 bucks a year while being better than some of them.

— Cory Salmon

I've used this software for the better part of four years now. I can't even begin to speak of how useful it has been to me during that time.

— Adam Novagen

One of the most useful free applications I have come across and one I use regularly. Keep up the good work. I know how much more difficult my life would be without FreeFileSync.

— David (UK)

Easy to use and works exactly as I need.

— kaffeinatedneil

Part 5/5

Thanks so much for Free File Sync (FFS)!!! Following problem has haunted me for years: Now that I have a 64-bit Win7 Pro OS that supports UNC paths up to 32K I thought the problem would be automatically resolved. But no, the dreaded 260 character path limit was STILL HAUNTING ME DAILY.

I have tried UNC paths, \ ? \ trick, SyncToy, Robocopy, Robomirror, Richcopy, and the MS Hotfix for long paths. Nothing worked, all failed for my needs. Then I found FFS. And it just works. I will donate at a later date.

— E. L. Faure

Excellent! Fast, easy-to-use, multi-platform and free: the best file sync tool, that I have ever used.

— Adrian Toth

FreeFileSync is an impeccable program that we recommend to each and every one of our customers for backing up their data.

— asapdata

Great product, I was able to synchronize all my data from my old HDD to the new one, after the transfer crashed using another software. Thanks for saving me hours of work!

— Michel Garcia

Used to use MS synctoy but it's so out of date you can see there is no future in it. Looks like sync center is the way to go for MS native but I have Windows 7 Home so I don't have that choice.

Anyway, came across this, judged it on downloads per week and gave it a go. Really impressed, easy to setup and with just a little reading you can get it to do realtime sync with RealTimeSync that comes with it!

Looks like it's maintained well and kept up to date (big plus) and I like the way it can use Windows Shadow Copy for locked files. Great stuff and thanks!

— jonafc

Been using for syncing a couple of directories across the LAN, pretty solid most the time. Thanks for the app!

— Karl Engstrom

Best program I have used in a long time. Keeps LOTS of my files in sync (between RAID NAS drives, between work laptop and virtual machines)... Keep up the great work!

— Jason Burgess

This project is clearly fueled by a great passion to provide the best possible end-user experience, and this is greatly appreciated!

— Jeffrey Gill

Now that the venerable FileSync has mysteriously stopped working on my PC, I am relieved to find FreeFileSync works well for me in similar ways.

— chishold

I use FreeFileSync to coordinate my data between desktop, laptop and tablet and it has never let me down. Thanks so much!

— Gina Paoli

Excellent and portable. It's my favorite solution to sync my devices and make backups. Useful options and intuitive interface. I just have created this account to say thanks to the author.

— jslopezg

FFS is highly capable and very fast. More importantly, it's very reliable: I synchronize about 250K files daily, with typically a few thousand changed and about a 500 MB in size and it has yet to mess up.

I used to use MS's SyncToy, but that name actually characterizes it all: a "toy". SyncToy would frequently get confused and want to move things in the wrong direction or show conflicts which weren't the case (esp. with MS network share drives).

One of FFS's strengths is how well it handles conflicts, though I have occasionally wished it had a one-click-for-the-newest button, it's really easy to select a group of files and right-click to send them left or right.

Also, FFS is orders of magnitude faster than Microsoft's SyncToy for high-latency drives, like WAN drives; synchronizations that would take several hours with SyncToy 2.1 completed in less than 20 minutes using FFS (and that was quite some versions of FSS ago).

The UI is adequate, with some very minor shortcomings, like not being able to reorder the list of directories being synchronized. Overall it's pretty easy to use, though I think filters and the two settings dialogs could be merged into a single concept / dialog. The ability to hook in an external compare tool is excellent, and it works very well with WinMerge to check exactly what is different between particular files.

The best sync util I've found. I am using it since version 3. It is the easiest way to keep a complete synced mirror from my laptop to my desktop user's folder. Highly recommended!!! A++++
