If the partition where the target path was located is FAT/FAT32, files larger than 4GB will not be synced to the target path. Because a single file larger than 4GB cannot be stored on a partition which is formatted with FAT/FAT32. Please re-select another target path and try again. If the partition where the target path was located is not FAT/FAT32, please view the product log, or contact our technical support and send the log folder in the installation directory to us.
The possible reason is that after the files or folders are synced to the target path, the character of files or folders path exceeds the maximum path character allowed by Windows system. Although the files or folders cannot be accessed, they are not damaged. You can access the files or folders by cutting the parent directory of them to another path with fewer characters. If they are still inaccessible after the cutting operation, please contact our technical support and send the log folder in the installation directory to us.
The possible reason is that SYSTEM user doesn't have permission to access the source files, but File Sync operates files based on SYSTEM user’s permission. Therefore, some source files cannot be synced successfully. At this point, you can add SYSTEM user’s permission into the security attribute of the file and then try File Sync again. If it still fails, please contact our technical support and send the log folder in the installation directory to us.
File Sync temporarily has not yet used an executing interface or a tray notification to show sync progress. You only can view the progress when creating a new task and it is unable to view it later. To determine how the File Sync is executed, you only can check the status of files in the target path or the log.
File Sync temporarily only supports one-way monitoring and one-way sync which means it monitors the changes in the source files and syncs them to the target path, but not to monitor the changes in the target path. Therefore, it will not perform a sync operation when any change occurs in the target path.
🔔 Note: File Sync tasks only support one-way sync. For example, sync from A to B. Do not create a File Sync task from A to B, and then create another task from B to A. Otherwise, it may cause circulating sync which will increase CPU usage, make system running slow, and even lead to the source files corruption.
Because File Sync will monitor all the subfolders and files (including temporary files) in the source folder, temporary files will also be synced when performing File Sync. To ensure data safety, the program provides the “target files will be deleted when deleting the source files” function in the File Sync setting.
