Somesystem files, however, are locked by the operating system while it is running. These files can only be defragmentedwhen they are not being used by the operating system. This is only possible at an early start phase of Windows, evenbefore the graphical login prompt appears. At this point, no system operating processes are enabled and you cannotstart any application. This phase is called Boot time defragmentation.O&O Defrag - 56
