Same problem. Last Defraggler run upped "disk used" space by 15GB.
Running Windows 7 Home Premium 64-bit SP1.
Always run CCleaner just prior to running Defraggler
Been using Free Version Defraggler well over a year now and download new versions as available. Settings are default. Symptoms started happening to me several of versions ago.
Based on Defraggler's drive map appears that additional space is mostly contiguous and in a separate area of the disk than "real data." Also appears additional space is not Defragged but is counted as Fragged space therefore the fragmentation % keeps climbing.
The attached Defraggler print screen may better communicate what I am seeing.
I was running Defraggler weekly, now much less often.
Any help or suggestions appreciated.
