Hi i downloaded a movie and it came in 2 parts. Is there a program that i can download that will put the 2 movie parts together and make it into 1 movie so i dont have to click on the other one.

download.com have a few good utils for the job. I did a search and it came up with these (http://download.com.com/3120-20-0.html?qt=avi+joiner&tg=dl-2001&search=+Go%21+). None of them seem to be completely free but most are limited by time, not functionality and I'm sure there are ways around that ;)
