Having recently experienced several sad trouble-shooting encounters with users, I've added the default that ForScore will create a zip file backup of its data once a month.

 

This is the same sort of file that you can create manually (which, unfortunately, most people don't) using the Data File Archive wizard from the main File menu.

 

These zip files are created in the same location used by that wizard. On Vista or Windows 7, that is normally

 c:\ForScoreFiles\ArchiveDATA

On XP it is normally

 c:\Program Files\ForScore\ArchiveDATA

 

If you really want to disable this, you can do so in Program Preferences.
