Wen looking in the C:\Windows folder of my XP Pro system I noticed a folder with the name $Ntservicepackuninstall. It was a hidden folder, Read only of almost 350 mb containing over 2,000 files. From its creation date it seems to have been produced when I installed SP2. I am always looking for ways of removing unnecessary items from my C: drive and if necessary storing them on another partition on which free space is not so important. I wonder whether it would be safe to move the folder in question. Presumably it would only be needed again if I decided to revert to the original XP, i.e. without sP2. Any advice would be appreciated, Douglas -- Douglas Harrison
