After stripping the file paths I can copy mobilesheets.db from Android to Win10 and it works fine. Thank you guys for your support.

@Sciurius:

I used db_reloc to modify the file paths in the database.

db_reloc.pl ...--src="/storage/emulated/legacy/_MobileSheets/" --dst=""
was not possible as --dst="" is considered as missing and causes the error message "Option dst requires an argument"

As a workaround I had to duplicate all my replace commands and keep the last subfolder, like:
db_reloc.pl ... --src="/storage/emulated/legacy/_MobileSheets/Songs" --dst="Songs"
db_reloc.pl ... --src="/storage/emulated/legacy/_MobileSheets/Fkbk0" --dst="Fkbk0"
and so on.
That works for me as I have to handle only three subfolders and it is done now.

But maybe you can allow --dst="" so that simply removing a part of a path is possible. It might be helpful for others and in other cases.
