In just a moment you can see how and what is fragmented on your hard drive. With this application tool it gives your hard drive a quick one touch quick defrag. So while you are not using the computer you can set the computer to defraggle and walk away and come back to a computer that is running much faster and smoother.
Defraggler is from Piriform which also came out with one of my favorite programs called CCleaner. Both these programs are completely free.
