Get past the visuals and defragging works more or less as you'd expect. You choose a drive; analyse it, launch a quick or full defrag; and then watch as the usual drive map keeps you up-to-date with progress.

Performance is great, as the program is based on Auslogics' regular disk defragger. But if you still don't have time to run a full defrag, no problem: Auslogics

Disk Defrag Touch also includes an "Optimize Programs" section which appears to defragment files relating to a particular application only.

There are some useful tweaks and settings. You can have the program delete temporary files before defragging, speeding up the process. An option to skip large file fragments also improves defrag speed without making much difference to your final system performance. Or you might tell the program to move system files to the beginning of the disk, which means defragging could take a lot longer, but you should see a faster system afterwards.
