SyncBack Freeware is the totally free version of the SyncBack program, which will help you both make backups and synchronize the contents of different files or folders with each other.
The synchronization of the files that SyncBack Freeware performs is not only between different folders on the hard disk, but also with the contents of CDs (of the CDRW type), CompactFlash, FTF servers, with other equipment through local networks or even with the compressed content of ZIP files.
Another of the SyncBack Freeware tools is one that allows comparisons between different files, but by size or date.
You can free download SyncBack Freeware 32, 64 bit and safe install the latest trial or new full version for Windows 10 from the official site.
