Sometimes it will allow you to view all the files contained within, when your Sansa or other MP3 player is connected to your PC via USB. Visit Linux.org for info on using Live CDs/DVDs for this procedure.

I use my mp3 for podcasts and therefore frequently delete files I've listened to. Unfortunately when I view the available files on my computer, some files don't show, but show on the sansa screen. Any suggestions in how to access the missing files? The Sansa doesn't allow me to delete files from its screen.
