How do you view .AVI files that end in a number???

Ok. now I have ASF and HJ split downloaded. The ASF won't drag and drop
anything into the bottom window, and neither one appears to recognize RAR files. But I apparently can't extract the second part of a 2 part movie without utilizing one of these programs. I read the part about making sure all the files have the same extension, but does that apply to RAR files or the new folders. So which is it, extract from rar and then join, or join while still in rar files? I wouldn't care in the least except I would really like to see the second part of this max clip.
I will be grateful for any advice.
