Actually to finish ToMACsh's Post, You actually don't have to have a bar active, it does it by native... all the way at the bottom of a finder window, it should say something along the lines of "88 items, 118 GB available"
Also if thats not the case, then if you can point out what to toggle on and off, that would be helpful, cause I have tried for a long time to make it go away, but it wont. (dont want it gone away now, since I like it, but cant hurt to know
)
**Sorry toMACsh if thats not where you where going or if thats not what you where trying to say
