Hi. I installed Defraggler a couple of days ago to add to a maintenance clean up for a friends pc. This pc is a few years old and I dont think any maintenance had been preformed. I did all the cleaning up and deleting of stuff and updating, then finished off with a defrag, with default settings. Before starting, Windows said there was 449 Gb free on the terabyte drive. After first defrag drive has 341 Gb free! Map still shows fragments so I run it again. Now there is 629 Gb free!! Map still shows fragments, run again. Currently at 60% with 11 hours to go but now showing 623 Gb free!!! Where has 180Gb of data gone? Im a little concerned as its not my pc.
Any ideas? Thanks
