I didn't know where this question would fall, so I decided to put it in General.
I've never had a problem with extracting .rar files in Gutsy but for some reason, when I tried extracting .rar for the first time in Hardy (I think), I got this error:
Could not open "GC.Y.A.H.pks.rar"
Archive type not supported.
The file, as you can gather from above is called: GC.Y.A.H.pks.rar
At first I thought it wasn't working because of all the periods throughout the name, but that's never stopped it before, so I'm clueless right about now
