I was curious, is there anywhere on the PS3 you can go to to find out how much space remains on your Hard Drive?

I've downloaded free junk like a maniac from the Playstation store (Most of it is just that - junk ), and I have no idea how much space is left on the internal drive. Is there a way? I'm talking something like when you go to the PS2 Memory Card, and it spells it all out for you in terms of space and such.

Thanks.
