Notes
- ^ Windows Task Scheduler "Idle" schedules and options settings will be applied to scheduled tasks.
- Defraggler's GUI only provides an interface to configure defragmenting activity in Windows Task Scheduler.
- Condusiv Technologies claims its InvisiTasking technology eliminates the need for scheduled defragmentation.
- UltraDefrag can be run in batch scripts and apply several parameters separately for each disk.
