About 5% to 10% is the guideline. Windows needs a minimum of 15% free space to defrag. But Diskeeper defrags with as less as 5% free space efficiently.
You can do it with a few megabytes, but about 8-10% of the drive is recommended. When the space is very low, the defragmenter takes longer.
To open Disk Defragmenter, click Start, point to All Programs, point to Accessories, point to System Tools, and then click Disk Defragmenter.
A fragmented drive results in slow read and write operations as the files are scattered all over the hard disk. Microsoft Windows provides defragmenter utility to defragment the hard drive. Go to Start --> Programs --> Accessories --> System Tools --> Defragmenter
Disk defrag AKA Disk Defragmenter is a way to reduce clutter and to "defragment" files. This essentially makes your computer faster in the sense that it can load files faster. This program also compresses files and clears up small amounts of hard drive space.

It's called disk defragmenting, Vista, Start Menu, All Programs, Accessories, System Tools, Disk Defragmenter It should be scheduled, unless you changed it, for 3 a.m. You can change that if you click Modify Schedule.

It can take from a few minutes to a couple hours. Sorry, but I've forgotten how to do it with xp. Hope this helps!
disk defragmenter pieces fragmented memory in the hard drive of the computer in question back together to speed computer performance. if u r trying to do this on a personal computer, then it doesnt matter at all. but u should run disk cleanup first or it may take awhile to defragment.
Notepad and disk defragmenter do not use the same resources. However, Notepad can be used to open disk defragmenter from the system file.

Some common reasons for problems in defragmentation are- (1) Not enough disk free space since the XP defragmenter needs atleast 15% free disk space to defrag. (2) Fragmented system files such as the Master File Table (MFT) or the Page File. The XP defragmenter cannot defrag these. You can clear up some disk space by doing a disk cleanup with the 'Properties' option by right clicking the drive in 'My Computer'. To get around these issues, especially (2), you'll need a third party defragmenter such as Diskeeper 2009. Diskeeper can also defrag in very low space conditions, as well as defragment the MFT and Page File. You may need to run a boot-time defrag after a conventional defrag to completely defrag these system files.
The Disk Defragmenter can be found by pressing the windows button + R and then type "dfrg.msc" without the quotations.
