    With a video converter like wonderfox hd video converter factory, you can convert the “undf” video and audio files to MP4, AVI, MP3 and other common files supported by VLC to fix VLC does not support undf problem.

  3. If you’re worried about playing only one Undf file or Ten files… U can transfer the files to ur Android tap rename.. After renaming you’ll be able to change its format.. Suppose my file name is “Rock Dance” u should simply write “Rock Dance.mp4”

    Then try to play it on Ur pc.. It will work..

    But as i said. U can rename 10 files on ur android.. Renaming much files will be frustrating for u..
