Sansa Fuze database does not list all songs stored in the Fuze and microsd card.

Only 5700 files viewable on the Fuze? The database size on the player is limited. Using long filenames, tag names, folder names, and having heavy file nesting is what reduces the number of files the player can see. People usually mention 8,000 as the limit, however the number it can see seems to be related to pathname and tag sizes. Some people did some experiments and made the filenames, folder names and tags very short, and made the file structure very simple(very minimal nesting), and found out that their player could see many more files. I think someone mentioned seeing over 10,000 songs on his Fuze by using two or three  letter filenames, tags and folder names and having very minimal nesting.
