How can you open undf with windows movie maker?
That is not a file format. Undf stands for 'undefined file'. Files used in Windows Movie Maker have to be compatible with the program as well.
How can I play undf format?
UNDF is an undefined file. This may be because it is corrupted, or it is still in the process of being downloaded, and therefore vital information is missing. It is not a file type. Another reason that the file is not playing, is that the media player used does not have the suitable codec for it. Try using other players (the one that does the trick when VLC says that the file is undf, is SM PLAYER)
Can you repair the undf video files?
Yes, one can repair undefined video files by reading and following instructions. If one knows the file format of the video file, one can simply add the extension manually by renaming the file with the correct extension. Such as renaming file extension video "bmp" to video "wmp." Should that process fail then a decoding program would be the next plan of action.
What do you need to open torrent games one is a 7z file but when when trying to open with VLC says it is an undf file the other is an ISO file any input appreciated?
A 7z file is not a video file so it cannot be opened with VLC. You need something such as WinRAR to open it. An ISO image is like a disc and needs to be burned onto a blank disc using something such as ImgBurn or CDBurnerXP. You need to have finished downloading the files first because an undf file means 'undefined' and that means it is incomplete or you are opening the wrong type of file since VLC can't open 7z files.
