Q. I do I combine multiple files into one file. I downloaded a movie from bit torrent but its multiple files. I can watch the movie with VLC media player but I dont want to have all these files when I can just have one.
As j-b said, if you have several watchable videos (such as AVI files) use a tool such as VirtualDub to join them.
If they are e.g. RAR archives (*.part1.rar, *.part2.rar... or *.rar, *.r01...) then you need to extract the file(s) first. Use a tool such as
7-Zip (for Windows anyway) then try and play the extracted video file in VLC.
Arite.
