On the Fuze itself in folder mode, the player will only show folders that contain files that are in a format that the Fuze supports. There is no stated limit to the number of folders that can be used on the Fuze, as this will vary. The limit is on the size of the song database, which depends on the number of songs, the size of the path names, and the size of all the tags.
Actually, there is one possibility if your files cannot be found, the Sansa likes to append the music database to save time during the refresh. This allows the possibility of an elusive error sending you for a loop.
You can correct this issue by deleting the mtable.sys file from the root. This is the music database file. If deleted, the Sansa builds a new one from scratch. Folder view also uses this file.
Are your folders very heavily nested? How many songs do you have? There is a limit to the size of the music database, and if there are too many songs then some won’t be seen by the player. Are your tags in in order?
if there are problems with your tags, it is possible the files might not be seen in folder browsing mode either, since folder browsing mode on the Fuze is not true folder browsing.
I had about 1 folder with 2 subfolders in it, so no, I wasn’t that nested.
After finding fsck.vfat on Linux, things ended up going wrong, so I had to make a new filesystem. It may not be QUITE
back to the original contents (with the demo stuff), but after some hacking about I seem to have it working again.
And now I’ll know how to do it again if the filesystem gets corrupt again. I suspect a session wtih my laptop
was interrupted – judging by which folder was corrupt.
