this is shown (a [not] existing folder on another index / drive with same name obviously):

That marked folder actually should not be existing on that USB Stick. This Stick (actually of the PIONEER E: volume / index) just inserted

does (and did) not contain two or more folders of the ones that are shown in its index. The other folders are on that drive. And the index in the folder panel seems to have a different drive letter, than the (same) index in the FAT Tab indexes in the options.
It appears there are folders / files / drive letters / drives or something got mixed up somehow. Or am I missing anything? Would there be a way to get that like it should be?
The (complete) indexing (after I changed the drive letter of the hard disk E: and changed it back to E:) lasted very long for only 60.000 files (without properties), may be 10, 20 minutes or even longer. Plus indexing the properties after the files were indexed.
