Video files are often just chopped into pieces without any specific regard for the video file format, which makes it very easy to reconstruct the original using cat. Typically such files are named after the original, with a trailing numerical extension. Eg: cat file.avi.1 file.avi.2 file.avi.3 [...] > file.avi You may also come across files which have been broken into separate independently playable files. I don't usually bother to reconstruct these, I just use a player which can play the files in sequence without too much of a pause. flv is passable, though it overlays the file name at the transition. You could join such files properly using video editing software, and various command line tools, which I haven't looked into recently enough to have suggestions. Be aware though that many such approaches involve decomposing the video and decompressing it, with loss of quality. To avoid that, the joining tool needs to be quite specific to the kind of compression used, including both the wrapper format, and the particular codec involved. If just concatenating the files back together isn't the answer, you should say what happens when you try to play the second file, and for an ideal result you may do better to ask in a video specific forum.

I have downloaded a 4 part video that had been split into parts for down loading and I wish to put back into a single file. Any one have any sugestions for a decent utilty for this.
I minor point is it plays the files at the wrong aspect ratio the correct being 4x3.
The files are a fairly rare german film of the history of the Schnellboots (literaly fast boats, the german ww2 torpedo boats)..
