This article describes the Disk Defragmenter tool included in Windows 98 and Windows Millennium Edition (Me). You can use the Disk Defragmenter tool to increase the speed of programs on your computer.
When a program is installed on your computer, the program's files may
be broken up over multiple locations on your hard disk. This is called
fragmentation. If fragmentation occurs on your hard disk, the performance
of programs on your computer is slower. The Disk Defragmenter tool
optimizes the performance of your computer by reorganizing the files on
your hard disk into contiguous blocks. When the Disk Defragmenter tool
completes the defragmentation of files on your hard disk, the performance
of your programs is faster because the files are arranged closer together.
NOTE: You can use your computer while Disk Defragmenter is running.
However, your computer operates slower and the defragmentation process
restarts if the contents of the drive you are defragmenting changes.
To start the Disk Defragmenter tool, use the following steps:
- Click Start, point to Programs, point to Accessories, point to System
Tools, and then click Disk Defragmenter.
- Click the drive you want to defragment, click OK, and then click Yes.
Appears to Hang at 10 Percent
In Windows 98, Disk Defragmenter typically runs an optimization process during the first 10 percent of the defragmentation process. The time that the process takes depends on the number and size of programs to be optimized. It may appear like your computer is hung. If you have previously run Disk Defragmenter without an issue and then converted to FAT32 and are now having an issue, see the following article in the Microsoft Knowledge Base:
Defrag Error Message: ID No:DEFRAG00205
