Hello there everyone, I'm using Defraggler, the latest version and I've got that problem.
It fragments my hard disk. Plus, it is full of films and music, they would not need a defragmentation.
It didn't happen with previous versions.
What to do? Is it a sort of bug?
Did you select regular defrag, or defragment free space?
Update: I left Defraggler working and it did a great job on the Archive (D:) but it is still increasing fragmentation on Local Disk (C:), which is the main disk where Windows is installed.
I don't know why but I'm doing another defrag and I'll let you know.
PS: Nope, I didn't select to defrag free space. :-)
