that player and it can not play wmv files. All video files would have to be converted to amv files. The wma files may not be able to be played because of DRM (digital rights management), however any any type of file can be stored on the player. The player may not be able to do anything with a file like an Office document, but it can store it as well as any other provided that there is enough room in the memory.
