I think I'm at the point to thank you all for jumping in! The case is discussed, my bad to interpret the option 'Import > System File Browser' (or whatever it is in English - I read it in German as 'System-Dateimanager') in a misleading way. I now understand that the method only allows to use alternative file managers by a totally different approach. Which is not based on file handling at all (you, Mike, say, it's handling an octet stream).

The only issue remaining is: Should I change my file handling within MSP? I initially found it handy to have the PDFs on my tablet in an openly accessible storage - that way, it's not only viewable with MSP, but with any app that shows PDFs. Quite a number of music I have consist in single lead sheets that I use in different contexts, others are full arrangements and need to be flipped by a BT pedal in a standardised band context. And yet others again consist in whole song books. With my ~1400 titles from around 500 files, I still prefer sorting them into thematical folders.

One more thing remains a request/wish for the moment: The longer I use MSP, the more versions I have from the same song - ChoPro and PDF versions, different keys, songs with different verses printed - different sheets for different occasions: Singing with children at school, singing in sunday service with elderly, playing piano, singing myself... As far as I see, there isn't an option to assign multiple files to one song, keep them all (including comments) and be able to blend in or out one ore another version, right? Or whatever mechanism would bundle part of those versions together. But this must have been discussed before...
For the moment, I try to identify the different versions by their title (with comments in brackets). But haven't included the Type tag into the library view yet - only the arrangement if it's written music (I use the Musician/Interpret tag for that).

By the way, I think you are doing a great job, Mike! I loved the rework of the annotations engine and use it massively. Couldn't live without. And I'm excited to be able to recommend MSP to iPad users now. Great mile stones. And as I may not have song mode any more on the next Nord Stage, I hope to get PC commands work from my tablet one day (I know they should).
