Does it support play by folder?

If you have a bunch of single tunes in a folder, you could use mp3tag. It’s free. Install it, open it, navigate to the folder with Change Directory, highlight all the files, make the Album or Genre something unique like Today’s Singles or Pepperoni Pizza, and then just use the Album or Genre category on the Sansa. Takes less time to do than to explain here. 

As much as I deplore tag-based navigation, I do use tags to store album, artist, title and other information, and MPTag has my highest recommendation for functionality, customizability, effectiveness, ease of use, speed and developer and community support.  It’s easily the best program of its kind, IMHO.
