I have just made a fresh install of windows XP PRo to a back up partition on my Hard Drive and have discovered that I have two 'mirror-image' folders for Windows each are 2Gb.in size and are identical and they relate to each other exactly, for instance if you move or delete a file from one it also moves or deletes from the other. I cannot delete (a Folder) as it is 'protected by windows'. One folder is named 'WINDOWS' and the other 'Windows'. I would like to solve this problem as I now want to make a Drive Image to a DVD but need to get rid of the additional 2.0Gb. of space. Never had this one before!!.
