Program to batch unrar?

Folks,
I have a folder that contains a number of sub folders containing multiple .rar archives.
Is there a program that will look at the top most folder and unrar all of the archives within the sub folders and delete the rar files when the extraction is complete? I use a program on my pc called 'unpacker' that does this perfectly, but would love an app for the mac.

i dont think so, but stuffit expander opens about any type of file except .exe so if you mean you want an app to open .rar get stuffit expander

Look up UnRarX a nice program to group your info in a single video file. When you download it, just open the program, then drag the file you want to compress in to the open window, it will do the rest.
