Thanks for that idea. It had an effect, but not what I wanted:

Before, when importing a song, a dedicated folder was created and a version of that sheet music (PDF) copied to the folder. Now, after disabling that 'create subdirectories' option, I get a new copy into the library root folder. Argh.

As I only recently started to directly create a local copy of my file from the NAS on my tablet inside the file selection dialog and directly select the newly created file: Could it be that the app checks the existence of the file from an older version of the library directory (before opening the file selction dialog) and then believes to need to copy that file? Even if I created it meanwhile?

That would be an explanation why I didn't encounter that problem before and also others don't seem so.

My problem is this: When I tidy up my library folder, I erase all those new subdirectories and will have a library entry with no sheet music (because I deleted the version connected - the file I originally connected to the song isn't the version stored in the data base entry). So I tidy up my folder and try to find all new songs that need a re-attribution of the sheet music. A hell of unnecessary work - only because I want to add a new song from my NAS in one step.
