# Multi-Tenancy with Subdirectories

If you want to copy another musician’s data into your SongBook+ without overwriting your own data, you can now create subdirectories in SongBook+, each with completely separate data.

Each of these directories will contain its own database (files SongBookMidi.sqlite, SongBookMidi.sqlite-shm, SongBookMidi.sqlite-wal), its own settings (file SongBookMidi.settings), and your own files (PDF, MP3,...).

Creating and accessing such subdirectories is unfortunately not possible via iTunes, but only through the Wi-Fi sharing of SongBook+’s folder or through the “Files” app.

More information on accessing via Wi-Fi sharing or the “Files” app can be found on the page [SongBook+ on iPad and iPhone](/english/readme/dateien-in-songbook+-einfugen/songbook+-auf-ipad-und-iphone.md#ref37432233).

Simply create directories that begin with "SBDATA\_", for example:

* SBDATA\_My data
* SBDATA\_Sandra
* SBDATA\_Thomas

The current folder can then be easily changed in the settings.

After selecting a different folder, SongBook+ will close and must be restarted.
