You can do this if you expose the database file in the storage settings, transfer that file to your PC, use an application such as sqliteadmin to open the database, run a query on the database to update all paths so they reference sdcard1 instead of sdcard0, then drop the database back on the database and reload the application. A command for updating the database would be something like:

UPDATE Files SET Path = replace(Path, '/sdcard0/', '/sdcard1/' ) WHERE Path LIKE '/sdcard0/%'

You'd obviously need to put the exact path in place of /sdcard0 and /sdcard1.

Crikey!

This is all very well for the more computer literate user, but this is an app primarily used by musicians not tech experts.  It might as welll be written in Ancient Greek for a lot of your customers.

Is there not another way to handle this problem?
