What I did on Windows XP, was the following first: Start to Control Panel to open System to Tab on System Restore to reduce the number of restore points. I have an 80 GB HDD and it is set to 1095 MB than the maxiumum. Then turn off System Restore. when it says:"Turned Off" uncheck the box to turn it back on. [You can create a new restore point to remove any items already deleted]. The I run Wipe & I will see only 2 boxes for MFT - the rest are cleaned out, sometimes my drive was 81% and now, 84-6%. I love Defraggler but I use CCleaner first.
