New Administrator Account?

I recently went into safe mode for something but I accidentally clicked on the Administrator account instead of my usual one (my username). I didn't do anything while logged in that account and quickly rebooted. Today, I noticed that there is a new entry in C:/Documents and Settings named Administrator, created the same day I went into safe mode. It has things such as Owner's Documents, Desktop, Start Menu, Application Data, Local Settings, etc. (much of the same things All Users and my user name folder has).My question is, is there any way to get rid of this - I'm assuming it's a new account - safely without harming anything in my computer? Is this something I should even be worrying over? The entire folder size is only around 16mb, but like I said, I can be obsessive about things like that.
