Deffragler took literally all my free space !

I used Defraggler two days ago, and my free space went from like 40% to 70%

So I called the friend who suggested me to use Defraggler, he told me to defrag one more time, so I did it this night, and now I literally have NO FREE SPACE !

I went from 40% to 90% of used space just by using defraggler !

I really need help now, can I revert all the work done ??

What operating system are you using? Win 7, Win 10 ?

Have you done a RESTART of your machine?

How much space are you using for system restore points?

Win 10

Yes I restarted the machine

And how do I know ?

Ok my friend helped me to find, my system restore point is using 143 Go :o

Do I delet it ?

Turn system restore off for your C drive.

Restart, and then turn system restore back on again

Allow Windows to manage the system restore space.

Then see what Defraggler says now.

I set restore point to 10%, then restarted the machine, now I recovered 40% of my free space which is good ( even tho I lost 20% since the first defragg, but not gonna bite the hand that feeds me lol )

Just about any 3rd party defrag tools can cause that, and more-so if they're allowed to do a comprehensive/full defrag. On Windows 10 specifically when using a 3rd party defrag tool I only have them deal only with fragmented files that they list in their file list after an analyze, plus it means the defrag finished ages faster too, and I allow Windows Defrag to perform the optimization on it's own automatic schedule - that way it isn't re-doing what another defrag program has done.
