Using this program you can perform all this tasks between computers, (Laptop, Desktop, Workstation, Server, over network LAN, WAN, VPN, USB), and with any type of storage media including external Hard Disk, Zip disk, USB flash drive, CD-RW, DVD, NAS (Network Attached Storage).
The comparison function lets you compare two files to know it there versions are the same. The synchronization lets you choose if you want to update the older one with the newer one, or viceversa.
