Downloaded 170 rar files, but no unrar possible??

[Alarm]

First of all, I'm a newby, so please be gentle

I downloaded a movie, 170 rar files, but it doesn't unrar, not with quickpar 0.9 nor with winrar 3.61
I also thought that rar files where numbered, but al these files have the ext rar (normally rar, r01, r02 etc) Am I doing something wrong here??

Which particular Movie did you download, and from which source?
