What softwar do I use to put split files of movie together into one file??

I have a movie but it's all in split into six parts (all .AVI) now I want to put the parts together THEN i want to put the whole movie itself after being out together into VDUB (or something else) to compress it because the movie itself is too big to burn to one DVD, even in different parts...

So, anyone know a good software to add parts of a movie togther?

thank oyu

 

You could check out this guide, I have never used it myself so cannot comment on it.
