I downloaded some files, but they’re not compatible with the Sansa Fuze or the converter. Please Help!
In iTunes, highlight the m4a files and right-click and you have a choice to convert to mp3. The Fuze will play mp3.
M4V has digital rights management garbage in it. You would have to burn them to CD and rip the CD with iTunes or another program to convert the files on the CD to mp3.
For M4A files, you can use a simple Apple Music Converterto help as it doesn’t contain any DRM protection. For M4V, you need a special iTunes M4V Converter due to the reason that it is combined with DRM protetion.
