I did some more tests. The only situation where it seems to work is on Android with the audio file in the same folder as .CSV and .PDF.
On Win10:
If the column "audio files" contains just the filename, the song can be imported, but the audio file is not attached.
If the column "audio files" contains any kind of path (/ or \, relative or absolute) the SONG is not offered for import.

It would be great if it worked like that:
- path of the audio file relative to the .CSV and .PDF file
- accept subfolders, at least 1 level
- allow both / and \

Thus it would allow copying the database file between Android and Win10 machines as it is currently the case with the relative paths feature for PDF files (which are relative to the MSP folder).
