[Zubersoft]

You only need to save the 41730Zubersoft.MobileSheets_ys1c8ct2g6ypr folder and your storage location (if they aren't the same thing). The LocalState folder under 41730Zubersoft.MobileSheets_ys1c8ct2g6ypr is where mobilesheets.db is (the database file) along with all of the configuration files. Those and the song files are all you need to restore your library.

The LocalCache folder gets automatically cleared by MobileSheets periodically, and I no longer use HockeyApp, so you can delete anything related to that. The LocalState folder is really the only folder you need.
