Hi,
many thanks for your advise.

In the meantime I found out, that a majority of the mp3 files were deleted and only the structure survives. No clue, how that happens, but after restoring the content all works fine.
Sorry for stealing time.

Cheers
Thomas

I have a new laptop with WIN11 and MM5. My previous laptop runs with WIN10 and MM5. In this configuration I had not this issue.
I defined a collection stored on my USB stick: "Path contains T: \"
Within the folder node the USB stick content is shown.
Clicking on "Location" within the collection nothing is displayed.
Which setting might blocks to display the content in "Locations" which is shown under "Folders"?

Does anyone has an idea?
