I am guessing that you are making a distinction between a file called “Folder.jpg” and another file called “Folder.jpg.jpg”. I believe that Windows would not equate these two as the same filename.
Bitmap or jpeg, I am told that Sansa Fuze+ supports them both. But the underlying issue seems to be in the folder and not in the art files. (Keyword: ‘seems’).
I still don’t understand why invisible files called ‘Folder.jpg’ are being secretly generated in so many of my homemade mp3 folders.
Maybe relevant or not…
Since I have no knowledge of associating mp3 extended file properties with album art files, I can’t discount the possibility that my mp3’s (which are mostly homemade) may have had a default ‘Folder.jpg’ file assigned to them. The software I use does not access any extended mp3 properties regarding “art”. So the problem could theoretically be right there.
