Hallo Geoff and Mike,

Thank you both, for your answers.

Mike, your suggestion, was what I was looking for! Thanks!

Geoff:
I edit my main database at home, on my desktop PC. There I keep All the edited pieces and the backup files of the main database.
I also keep a copy of this database on a cloud folder, which I actualize/synchronize after each edit.


For concerts I use different devices (laptop, smartphone, tablet etc.) and play with different people/ensembles/bands. All devices that will be used for a rehearsal/concert are being synchronized with this cloud folder.

So until now the people, who played with me (who also use MobilSheets, of course) got access to my main database. All 750 Mb of it. Even if our setlist consisted of only 5 pieces.
Additionally to that, when I play solo, most of the times, I do not need to have my main database on my tablet (for example).
It slowly needs too much space (which I sometimes, depending on the device, I do not have)  and the synchronization time is getting longer.
Finally, although the performance is not really being affected by the amount of free storage space, this is,  in the long term, still an additional concern for me.

Many greetings!
