... but I wanted to say that I've made some significant improvements to the handling of directories when restoring backups.

Great! Are these improvements already in the beta download?

The file paths must start with the storage location in order for this to work.

This is reasonable. The 'new' androids (well, since several years ago) impose restrictions on access of the storage devices so I'm starting to get rid of the idea of file placement all over the place while still expecting all tools to know how to deal with that.

Since I can access Android/data/com.zubersoft.mobilesheetspro/files from outside (adb, ssh, rsync) there's no reason for me to put the files elsewhere. My goal is to make music, not to make your life hard   .
