Microsoft's preference is that common user data (not data specific to a single user) be stored in a hidden folder called C:\ProgramData that has some rather restrictive permissions set.
I'm ignoring Microsoft's wishes.
•On a normal Vista/later, ForScore by default will use a folder called C:\ForScoreFiles in which to store all of its data and license files. This folder is created by the Vista Setup Wizard; you can also use that wizard to put your data files in a different location. NOTE: the /data, /data1, etc. switches will work normally with Vista/later to point the data and INI files at a folder of your choice. However, other files (such as zip archive data files and CSV export files) will still be written within folders inside of C:\ForScoreFiles, or whichever other folder you may have selected with the Vista Setup Wizard.
•If you are running ForScore from a USB thumb drive on a Vista/later machine, it will use the 'old' data locations that non-Vista installations still use. This way, you can move a USB stick from a Vista to a non-Vista machine and not have to chase the data.
