(I replaced Win defrag as default, with DF) Boot Time Defrag Boot-Time Defrag – defrags the system disk during the boot time, before the whole operating system is loaded. This allows Defraggler to defrag the files which are blocked after the operating system is loaded. At the moment following files are defragmented during the boot time defrag.
Using Disk Defragmenter in Windows Vista. Using Disk Defragmenter in Windows 7. Defragment and Optimize your hard drive in Windows 8. How to defragment and optimize your drive in Windows 10. Perform advanced disk defragmentation with Defraggler from Piriform. If you want to go the extra mile with optimizing your HDD, remove the swap file before. Boot Time Defrag Defraggler has a Boot-Time Defrag option which allows you to defrag files that are normally locked by the Operating System before the operating system is fully loaded. To enable Boot-Time defrag: In Defraggler's main menu, click Settings, and then click Boot Time Defrag. Solution: Run a defrag (it may take a LONG time if it's never been done before (I've seen some reports of 3-4 days, but that's probably very unusual. If the defrag won't run or takes longer than. Quicker System Boot Time. As your computer getting older, it takes longer to startup your computer and begins to work. Smart Defrag helps fix this problem easily. Configuring Boot Time Defrag feature, those files on HDD that cannot be moved while system is running can be quickly defragmented for faster startup.
System Files is the designation that PerfectDisk uses to identify important files that the operating system uses at runtime to operate your PC. These include the Windows paging file (pagefile.sys), the hibernation file used to support sleep mode on desktop Windows PCs (hiberfile.sys), and operating system files too numerous to mention (primarily found in the %systemroot%--often C:Windows--and %systemroot%System32—often C:WindowsSystem32—directories. The constraints vary by operating system (Windows Server 2003, Windows XP, Windows 7, and Windows Vista and by file system format (FAT/FAT32/exFAT or NTFS).
Depending on whether or not the drive is a system drive, or some other drive that PerfectDisk can't lock, offline/boot time defragmentation may or may not run on the drive(s) you select in the drive pane, when you click the Boot Time Defrag tool in the Tool Bar of PerfectDisk. As long as PerfectDisk can lock a drive for exclusive access at runtime, it will defragment system files immediately. But for a Windows system disk or any other locked drive—one, for example, where a paging file might reside in whole or in part—attempts to defragment system files at runtime will usually fail.
You can also set the Boot Time defrag to 'ON' for a drive in the Drive List area. In this case, the boot time defragmentation is performed on the drive during next reboot of the machine.
The three types of files which may need to be defragmented at boot time are:
Boot Time Defrag
§Pagefile - This is your virtual memory file (Pagefile.sys). This file is exclusively locked by the operating system and can only be placed by a Boot Time Defragmentation pass.
§System Files - These are operating system files, such as the Master File Table, the hibernate file and other metadata files. Depending on the operating system and file systems, some of these files can be defragmented online and some at boot time.
§Directories - On NTFSThis is one of three file systems supported by Windows. The other two are FAT and FAT32. NTFS is faster on large drives, and provides file level security which is not supported with FAT or FAT32. NTFS also support compression and encryption.

A boot defragment is a special version of the defragmentation function on computers. It rearranges data so the files used during the booting process are physically next to one another on the hard drive. This can speed up the boot process.

Defragmentation involves rearranging the physical location of data on a hard drive. It undoes fragmentation, which is caused by the fact that when a piece of data is deleted from a computer, the resulting gap won't be filled if the next piece of data to be written doesn't fit in the gap. This can lead to the data being arranged in an inefficient manner.
The defragmentation process rearranges data so it is physically organized in the most efficient manner. This means the computer can access each piece of data more quickly: the difference is only a small fraction of a second each time, but it all mounts up. The process is somewhat like tidying up belongings scattered on a bedroom floor. Once this is done it is much quicker to both find and reach each particular item.
A boot defragment carries out the same task, but dealing specifically with boot files. These are the first files that load when a computer starts up. They are the files required to load the operating system into the computer's memory, along with the files to start up any program the user has set to run automatically when his computer starts.
Since Windows XP, Microsoft's operating systems are set up to automatically run a boot defragment. This is not controlled by the user and instead runs when the computer has been idle for a certain time, usually between five and 30 minutes. The boot defragment runs in the background, meaning the user is unaware it is running.

Although the boot defragment is set to run by default, it is possible for it to be inadvertently switched off, for example by an application. A user who is confident enough to run the Registry Editor can check whether this has happened and switch it back on if needed. This is done by opening up the Registry Editor and going to HKEY_LOCAL_MACHINESOFTWAREMicrosoftDfrgBootOptimizeFunction, then checking that the value next to 'Enable' is set to Y rather than N.

While a user can't directly force the boot defragment to run, there are two indirect methods. One is to simply leave the computer with no applications running for at least half an hour, which will make the computer run the defragment as long as the feature is switched on. Another is to force the computer to run all tasks it is set to run when idle, which includes the boot defragment. This can be done in 32-bit editions of Windows by clicking on Start, then Run, then typing Rundll32.exe advapi32.dll,ProcessIdleTasks and clicking on OK. As this runs multiple tasks, it is likely to affect computer performance until these tasks are complete.
The Apple Mac operating system does not have a built in defragmentation feature. The official recommendation, if a disk becomes overly fragmented is to back-up the contents, use the Mac system's initialization feature on the disc and then restore the data. As this is more troublesome to carry out, it is best saved for serious cases of fragmentation. The file management systems on most recent editions of Linux-based operating systems do not have built-in defragmentation features. There are a variety of third-party applications that can defragment a Linux-based drive though.
