No, I didn't see any file changes like a new restore points or files moved to the Recycle Bin. And what are pagefiles? And what do you mean by hibernation. I don't want to empty all restore points because they're usually my last hope when I get problems. Nope, I didn't use Windows Update, rip a DVD, or download new software before the defrag. The space was being taken during the defrag. Seriously, why did it take 20 GB? I feel like I don't want to defrag anymore because it just takes the used space ((

Hi, The free space was 99.6 GB before defragmenting. After the defrag, it lowered to 82.8 GB. Right now it's 82.0 GB free of 185 GB... What's happening? Is the space getting lower and lower? My antivirus is avast! Antivirus. I also have Malwarebytes Anti-Malware and Anti-Exploit. Haven't tried Safe Mode yet...

Hi mta, Thanks for the reply. Those three options were already ticked when I defragmented. I also ran CCleaner before defragmenting. I checked CCleaner for my restore points and I didn't notice any new points. The last was when I uninstalled Java. I uninstalled Defraggler for a while I guess I made a wrong decision in stopping the defragment process. But why do you think the fragmentation still increased when the three options mentioned were already ticked? And what are Volume Shadows? I'm sorry, but I'm a very inexperienced user. Do you know a solution to stop the used space from increasing? Thanks again. Update: After waking up this morning, I decided to reinstall Defraggler. When I analyzed the C: drive, it was at 5% instead! Why is this happening?

Hi, I decided to do a full defragmentation of my C: drive for the first time this day. The defragmenter I use is Defraggler by Piriform. When I analyzed the drive, it detected 13% fragmentation. After that, I clicked the 'Defrag' button to start the defragmentation processes. I thought it was going fine. At about 50% of the process, it was 10% fragmented now. But then I noticed that the used space increased from 86.3 GB to 103.2 GB! So I stopped the defragmentation. This was surprising. After stopping it, I decided to analyze the drive again to see if the fragmentation when low. At my surprise, it went HIGH! From that 10% fragmentation, it increased up to 37% fragmented! I was shocked. I went to Windows' built-in Disk Defragmenter to see if their analysis were the same. At my surprise again, it said 2% fragmented! I was confused. I don't even know which one is accurate now. Defraggler or Disk Defragmenter?!? I don't know which one is the problem. Is it Defraggler or Windows? Why did defragmenting make the drive more fragmented? Why did the used space increase? Should I try using a different defragmenter? Should I uninstall Defraggler? Info: OS: Windows 8.1, 64-bit Defraggler Version: v 2.19.982 C: Drive Capacity: 185 GB
