FreeFileSync is an open source software for Windows, macOS and Linux. FreeFileSync is essentially a folder comparison and synchronization software that creates and manages backup copies of all important files. Instead of copying every file every time, FreeFileSync determines the differences between the source and destination folders and transfers only the minimum amount of data required.
FreeFileSync 11.21 updates are as follows:
Support volume GUID as path \\?\Volume{01234567-89ab-cdef-0123-456789abcdef} (Windows)
Avoid bidirectional conflicts when changing the case of folder names
List hidden warnings in options dialog
Fixed buffer overflow when receiving SFTP server banners
Crash dumps are created even if crash handling inside FFS is not enabled
Log when the error occurs, not when the error is reported
Swap sides: ask for confirmation only after comparison
Updated translation files
