This option is the recommended option and is selected by default . If selected, PerfectDisk optimizes the location of the files needed to start your computer. This decreases the time necessary to reboot your computer, so you boot quicker. If not managed by the Operating System or PerfectDisk, your computer could become unbootable if a file needed to boot the system is moved beyond the BIOS limit of your computer. This is a subset of the files listed in the layout.ini file (i.e. only those needed to boot the operating system).
Let PerfectDisk Manage all layout.ini files
The file stores every file that is accessed from the moment you power up your computer to one minute after the desktop appears. By placing files on the disk in the exact order recorded in the layout.ini file, your machine boots faster. With all Windows versions starting with Windows XP through Windows 7, Microsoft includes a prefetch routine, which reads this file and loads the files in memory prior to them being needed. In this way, the operating system can access the files faster during boot up. If selected, PerfectDisk defragments and places all the files listed in the layout.ini file in order, starting at the beginning of your disk. This list contains all files loaded by Windows from the second you turn on your computer until about 1 minute after the desktop appears. This list not only contains the files needed to boot, but also the applications you routinely start after the system has booted.
