Hi,
I've just downloaded defraggler free, and as it is running the used space keeps going up and up.
Why is this?p
Thanks
. . . as it is running the used space keeps going up and up.
Likely VSS expansion. Tick ☑Stop VSS . . 
. . if you are concerned.
this doesnt work, still uses more space....
You can shut off your System Restore during the defrag. That would prevent restore points from being created, but it'd also delete previous ones.
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.

They are Shadow Copies (Restore Points). Your system creates Restore Points by updating Windows, running a defragmenter, etc. You can delete some of them with CCleaner's System Restore Management, thereby reclaiming free space. But with all the free space you have, you shouldn't be concerned.
Defraggler will exclude them from the count if you do this.
so what is the answer to my problem?
there is only 2 restore points in my system... defraggler has taken around 9GB free space
Thank You Kroozer
VSS doesn't list itself as a restore point.
I regained 25GB to my drive when I removed all but the most recent VSS this month; it's not something I'd do often as I use the VSS copies a lot, but every so often it's nice to regain the space.
defraggler has taken around 9GB free space
Defraggler doesn't take free space, but Windows will expand VSS somewhat during a drive defrag.
I suggest you install and run either WinDirStat or TreeSize to determine what is using the 9GB.
i see that, but i dont get what could suddenly take up 9GB during a defrag
EDIT:
seems to be a .sys file...
pagefile.sys is 5.6GB as it is..
