Guys, use 7zip!
Seriously, freaking WinRAR!? For what- archiving the album of .mp3s you downloaded from napster over the course of an entire evening with your state-of-the-art, 38880 baud, dial-up modem?
I kid, but seriously: www.7zip.org.
EDIT: If you’re on a mac, use this instead (it’s a 7zip port) www.kekaosx.com/
YOU ARE A SAVIOR!!!
