How can I get rars to unpack into one single folder?

[Bloopie]

I keep finding that my rars have been unpacked into multiple folders within the unrar folder. Sometimes the contents of the rars are inside 3 or 4 of them.
Is there a way to get Alt.Binz to keep all of the unpacked contents into one folder?

Have you checked the Unrar options? I've also made the same mistake with the Download and Unrar options.
When not settings these options right, you're creating lots of folders.
