Hi there nickmisky , welcome to PCHF.
So treesize says only 130mb total is used on youre C: disk? ( (C

and C:\ is the same) and you have WinXP installed? That cant be right.
So youre C: disk is 10.600 mb and 9200 mb is used? If you go to you C: disk and select all files and folders there and rightclick and select properties , what size says it then??
