Defraggler

Very nice defragmenting application.

Prefer it to most.

For me defragging is REALLY slow, and my drive isn't reading nor writing 90% time defraggler is supposedly working with the disk. Back to Diskeeper for the time being.

Like all other Piriform products is this also a must have

Awesome app for GUI or command-line usage (df.exe in the program folder). It is faster and does a better job than the Windows default defragmenter (XP or Vista) and the ability to only defrag a certain few (or one) files is great. Disk checking and freespace defrag are also very useful, and the option to drop the program's priority makes it almost invisible on CPU usage (gaming and defragging is now possible)!

I install it on every computer I work on, and it hasn't disappointed anyone yet.

Very good defrag program which works on 64 bit vista. Much better than windows own.

Is good defrag a file per time. Very functional and usefull defrag tool.

Great defrag tool. Better than the standard Windows defrag tool.

Great defrag tool.

This one is alot faster than the original program that comes with Windows, so I don't mind defragging my files often.

easy sw

Defraggler is faster than other defrag programs and is actually the only one to really solve the puzzles on your hard disk!

JKdefrag getting less resources and works faster, I use Defraggler when I want to defrag just some big fragmented files and I want to defrag just those file. Also defraging the free space of HDD is good with Defraggler.

Easy to use and very efficient.

It did speed up my computer...
