- Information
- Disk Defragmenter
Disk Defragmenter runs exclusively within the Windows interface. No MS-DOS version is included with Windows 95.
System performance sometimes seems to get slower as time goes on. While this is often caused by adding programs that use more memory, it can also be caused by programs reading from and writing to the disk so often that information becomes fragmented (no longer stored on the disk contiguously). This doesn't cause data loss, but a heavily fragmented disk can affect machine performance because it takes longer to find and piece together fragmented files.
In the Windows 3.x environment, it was sometimes difficult to determine why performance was lagging, but Windows 95's Disk Defragmenter makes it easy to monitor and maintain system performance so that you can identify problem issues and remove them. If system performance starts to drop off, run Disk Defragmenter to see if it helps by reducing disk access time.
Click Start, point to Programs, Accessories, System Tools and click Disk Defragmenter. When it starts, select the drive you want to check.
Like ScanDisk, Disk Defragmenter does not check CD-ROM and network drives, or drives created with the MS-DOS ASSIGN, SUBST, or JOIN commands. Refer to the Windows 95 Resource Kit for a complete listing. You can use Disk Defragmenter on a DriveSpace or DoubleSpace drive, but do not use it on drives compressed with programs other than Microsoft's DriveSpace or DoubleSpace unless their documentation says to: doing so could cause data loss because different compression programs store information differently. Use Disk Defragmenter only on DRV/DBL spaced drives.
When you have selected the drive to defragment, the utility checks the drive for, reports the amount of fragmentation, and suggests whether you should defragment now or wait.
If the amount is sufficient to make defragmentation advisable, Windows 95 recommends that you start the disk defragmentation process. You can use other programs while it runs in the background, but it can be CPU-intensive, causing other programs and Disk Defragmenter to perform slowly. For instance, a program that does a lot of reading and writing to the disk makes Disk Defragmenter start over. Displaying the detail also makes it run slower. When you use Disk Defragmenter, it is best to schedule a time during which
you are not using your machine.
Use the Start button to start Disk Defragmenter, or:
1. Double-click the My Computer icon.
2. Secondary-click on the C drive. This is the right button on a external mouse or the smaller mouse button
on a keyboard mouse.
3. Click Properties on the Context menu.
4. In the Properties dialog box, click the Tools tab. If you start Disk Defragmenter here it defaults to the
specific drive you have selected, and Windows tells you how long it has been since it was used on the
drive.
5. Disk Defragmenter is also located in the System Tools folder with ScanDisk and Backup.
