I'm sorry for the late reply.
Briefly speaking, this feature is recovery the available free space, but not defragment the files fragments and optimize the files and folders of the disk.
Thanks Flykite. Maybe something should be on help files as the word “defragment” will give the user a false sensation. In fact, on my tests, the free space does not increase after compacting the snapshots. Why?
I’ve uninstalled CTM and the results are in the screenshots.
Are the files restored to the same “position” on disk after the uninstallation?
I mean, is the fragmentation of the snapshots reflected in the disk after the uninstallation?
It’s not that bad compared with Windows system restore, but, anyway, disk has quite a lot of fragmented files (512) and not optimized also.
