An excellent synchronisation tool, recently revised by the author.
It’s already possible to synchronise two folders on a computer’s hard drive, but syncing folders across different media forms (e.g. USB or CD) is slightly trickier. DSynchronize is a standalone tool for periodically syncing two or more folders on your hard drive across different media such as floppy disks, LAN, USB stick, CD, DVD and on the server. You can also specify the time and date of synchronisation and create filters for other factors should you wish.
