If you don't want to pay for the commercial version, then Auslogics also have a free build available, but unsurprisingly it's much less powerful. And you can tell the program not to run at all when a particularly demanding application is running, so if you launch your favourite games, say, you can be sure they'll get 100% of your system's resources.

In just a few clicks you can limit the maximum use Disk Defrag Ultimate will make of your CPU or hard drive. So you might choose to defragment an individual file, a folder, or an entire partition the program can run before Windows launches, enabling it to defrag system files which would otherwise be locked a scheduler can run unattended defrags whenever you like, or you can even leave Disk Defrag Ultimate running in the background, so it can detect and eliminate fragmentation just as soon as it appears.Īnd if you're worried about the program slowing you down, then don't - it's not going to be a problem. While leaving a little free space after specified files also helps to reduce future fragmentation.Īnd there are even more ways to run a defrag job. The program provides multiple defrag algorithms, for instance: it can optimise access according to file access time, modification time, Windows own prefetch layout, or you can even manually define which files you'd like written to the fastest part of your drive. Auslogics Disk Defrag Ultimate 4 is a very powerful defrag tool which provides everything you'll need to keep your system running at peak performance.
