FreeFileSync Software Function Introduction
FreeFileSync is a remarkable file synchronization software that stands out for its comprehensive set of features, catering to users with diverse file management needs.
Multi - Rename Function
The multi - rename function in FreeFileSync is a boon for those who need to manage multiple file names in one go. It simplifies the often - tedious task of batch file name modification. By simply selecting the target files in the file list and right - clicking to access the "Rename" option, users can enter a dedicated rename window. Here, they are presented with multiple flexible operations. For instance, the "Insert Text" operation allows users to insert specific text at a desired position within the file name. This is extremely useful when, for example, you want to add a sequential number to a series of files for better organization. The "Append Text" option enables adding text at the end of the file name, which can be used to mark files with relevant information like the creation date or a project - specific tag. Additionally, users can easily "Remove Text" from a specified position in the file name or even "Delete Text" entirely, based on their requirements. What's more, FreeFileSync has the intelligent ability to detect patterns among selected files' names, highlighting similarities and making consistent renaming a breeze.
Comparison Modes
Accurate comparison between two folders is the cornerstone of effective file synchronization, and FreeFileSync offers three distinct comparison modes.
File Time and Size Comparison : This mode categorizes files according to their modification time and size. If two files with the same relative path have identical modification times and file sizes, they are regarded as equal. It is highly efficient for regular synchronization with a backup location, as it can quickly identify most file changes. Files are classified into categories such as "File exists on one side only" (either on the left - hand side or the right - hand side), "File exists on both sides" with sub - categories like "Different date" (indicating which side has the newer file), "Same date" (signifying equal files), and "Conflict" (when files have the same date but different sizes).
File Content Comparison : This mode ensures that files are marked as equal only when their content is an exact match. It is indispensable for scenarios where bit - by - bit consistency between files on both sides is crucial. Although it is the slowest comparison method, it serves as a reliable fallback option when modification times are not trustworthy, such as in some mobile device or legacy FTP server operations.
File Size Comparison : In this mode, files of the same size are considered equal. It is particularly suitable for situations where file modification times are unavailable or unreliable, like in certain MTP and FTP synchronization scenarios where a content - based comparison would be too time - consuming.
Moreover, FreeFileSync allows users to configure how symbolic links are handled during the comparison process. Options include excluding symbolic links from the scan, treating them as the actual objects they point to, or including the symbolic link object directly.
RealTimeSync for Automated Synchronization
RealTimeSync in FreeFileSync revolutionizes the way file synchronization is done by enabling automated operations. Its core function is to execute a command line whenever it detects changes in the monitored directories or when a previously unavailable directory becomes accessible, such as when a USB - stick is inserted. Setting up RealTimeSync is straightforward. Users can start RealTimeSync.exe located in the FreeFileSync installation directory. They have the option to either manually input the folders they wish to monitor or import an .ffs_batch file through the menu (File → Open) or by simply dragging and dropping. Once RealTimeSync is up and running, it directly receives change notifications from the operating system, eliminating the need for continuous polling. It also incorporates a user - configurable idle time feature. After detecting a change, it waits for this idle time to pass to ensure that the folders are not in the midst of heavy use before executing the command line, thus optimizing the synchronization process.
Progress Monitoring
During the file synchronization process, FreeFileSync provides users with a clear and detailed progress display. This allows users to closely monitor the progress of file copying, deletion, and other operations in real - time. The prominently displayed progress bar shows the overall progress percentage, giving users a quick overview of how far the synchronization has advanced. Additionally, for each individual file operation, detailed information is available, including the file name, the specific operation being carried out (such as copying, updating, or deleting), and an estimated time remaining. This level of transparency ensures that users can accurately gauge how long the synchronization process will take and ensures that everything is proceeding as expected, providing peace of mind during potentially time - consuming operations.
Flexible Configuration Options
FreeFileSync offers an extensive range of flexible configuration options, putting users in complete control of their file synchronization settings. From the main interface, users can easily access a plethora of settings. They can customize synchronization rules to a great extent, such as specifying which files or folders to include or exclude from the synchronization process. For example, it is simple to set up filters to exclude temporary files with extensions like .tmp or specific folders that are not relevant to the synchronization task. Moreover, users have the convenience of saving different synchronization configurations for future use. This means that they can quickly switch between different backup or synchronization scenarios, whether it's for backing up work files, personal documents, or media files, without having to re - configure the settings every time.
SFTP Support for Secure Remote Synchronization
In an era where remote file management and security are of utmost importance, FreeFileSync's support for SFTP (Secure File Transfer Protocol) is a highly valuable feature. This enables secure remote file synchronization. To establish an SFTP connection, users simply need to navigate to the folder selection area and choose the "SFTP" option when adding a new folder. Subsequently, they will be prompted to enter the server address, port number, username, and password. Once the connection is successfully established, synchronizing files between the local machine and the remote SFTP server becomes as seamless as working with local folders. This feature is especially beneficial for users who need to back up their files to a remote server or share files securely over the internet, ensuring the integrity and security of their data during transfer.
Binary - Based File Comparison
The binary - based file comparison function in FreeFileSync is closely tied to the "Compare by File Content" option. When this option is selected, FreeFileSync delves deep into the binary content of files to determine their exact identity. This method offers a more accurate way of comparing files compared to relying solely on file size or modification time. In many scenarios, files can be modified in ways that do not affect their size or modification time, such as when minor changes are made to the content within a document. In such cases, the binary - based comparison can precisely identify these differences. The settings related to this function are conveniently located within the comparison - setting section, allowing users to easily select this binary - based comparison method as one of the available comparison variants according to their specific needs.
In summary, FreeFileSync is a feature - rich file synchronization software. Its diverse range of functions, from file name management to secure remote synchronization, combined with its user - friendly interface, make it an ideal choice for users across various fields who require efficient and reliable file management solutions.
