Short description of Autobackup-Pro 3.2: Autobackup makes a copy of your modified files each day into a separate folder.
You create a list of paths to check, and each day when the program runs it makes a backup copy of all files in those paths which have been modified since the last backup.
It will also create diary entries for use by Acute Software's Electronic Diary, so you can see at a glance all the files you worked on in a particular day/week/month.
