and is there anyway you can remove the files contained in it? My folder on my C drive which is separate from my other files under document settings show this recycle to hold over 7.3 GB of files yet the recycle bin on my desktop is empty .. confused on what this is..

I'm trying to free up some space on my C drive as it only has 4.5 GB left and the remaining 23.5 ( 30GB drive) are my exisitng folders and files .
I have all my photos and music on other drivers and I recently picked up an external 680 GB Seagate Hard drive. so everything is backed up that I think is important but am always looking for more space ..

any advice???
