Defraggler

Scheduler

If you want to schedule a defrag at a later time, or if you wish to set Defrag to run regularly without you having to lift a finger, then Defraggler has a scheduler tool just for this.

 

To schedule Defraggler to run at specific times:

  1. From the main window, select Settings, and then click the Schedule option.
  2. Select the drive you want to schedule Defraggler to defragment from the Drive drop-down box.
  3. Select Schedule defragmentation for chosen volume.
  4. In the Settings area, choose how often you want Defraggler to run (once, daily, weekly or monthly) or when (at Startup, at Logon, when idle).
  5. Select the date and time when you want Defraggler to start.
  6. If you want to add a scheduled entry for another drive, repeat Steps 3 to 6, selecting the new drive from the Drive drop-down box.

In the Advanced options you can change the following settings:

Timeout - Defragmentation will stop when it runs longer than the time set
Idle - Defragmantation will be started when the computer is idle for a set time and stopped when it ceases to be idle
Power - Settings for laptops running on batteriesSchedulerAdvanced

Notes:

  • Defraggler requires the Windows Task Scheduler service to be running for scheduling to work.
  • Defraggler runs as a scheduled Windows task. You can view the task in the Scheduled Tasks applet from the Control Panel.
  • The scheduled run will not occur if the Defraggler window is already open - even if the Defraggler window is idle.
  • Defraggler has two versions: Defraggler.exe, the program with a graphical interface, and df.exe, a 'silent' program that runs without any visible notification. df.exe is the version of Defraggler that runs as a scheduled task.
