Scheduling Defragmentation
Defragmentation is the process of analyzing local volumes and consolidating fragmented files
and folders so that each occupies a single, contiguous space on the volume. This allows the
system to access files and folders and save new ones more efficiently. Because
defragmentation consolidates files and folders, it also consolidates the free space on a volume.
This reduces the likelihood that new files will be fragmented.
Defragmentation for a volume can be scheduled to occur automatically at convenient times.
Defragmentation can also be done once, or on a recurring basis.
To schedule defragmentation for a volume:
1. On the primary navigation bar, choose Disks.
2. Click the Volumes tab.
3. Select the volume to schedule defragmentation.
4. In the Tasks list, choose Schedule Defrag.
5. On the Manage the defragmentation schedule for [VolumeName] page, select the
Schedule defragmentation for this volume check box.
6. Select the frequency: Once, Weekly, or Monthly.
7. Use the remaining controls to specify when defragmentation will occur. The available
controls change according to the frequency that is selected.
8. Click OK.
To disable defragmentation for a volume:
1. On the primary navigation bar, click Disks.
2. Click Volumes.
3. Select the volume to disable defragmentation.
4. In the Tasks list, choose Schedule Defrag.
5. On the Manage the defragmentation schedule for [VolumeName] page, clear the
Schedule defragmentation for this volume check box.
6. Click OK.
Note: Scheduling defragmentation to run no later than a specific time prevents the defragmentation
process from running later than that time. If the defragmentation process is running when the time is
reached, the process is stopped. This setting is useful to ensure that the defragmentation process ends
before the demand for server access is likely to increase.
