Defragmentation is executed in the background while the system is running and normally optimizes most files. Some system files, however, are locked by the operating system while it is running. These files can only be defragmented when they are not being used by the operating system. This is only possible at an early start phase of Windows, even before the graphical login prompt appears. At this point, no system operating processes are enabled and you cannot start any application. This phase is called Boot time defragmentation.
It is now possible, using this feature, to defragment a file which is being used exclusively by the operating system. Depending on the operating system, for example, this can be the swap file, the registration database as well as the MFT (Master File Table).
- The options for the boot time defragmentation can be easily set in the settings dialogue under boot time defragmentation.
- Please select whether you want to useboot time defragmentation regularly at every system start or one time only at the next system start.
You can also disable boot time defragmentation.
