Defrag System Files

There have been a number of blogs and articles written in recent months on the topic of best defrag software. I think that just begs the question, what would you want in your best defrag software?

At a minimum, you would want any defrag software to defragment all of your data files. The Windows 7 defragmenter and the free defrag utilities do a decent job in this regard, but the disks still re-fragment quickly. File defragmentation is just half the job, to truly hinder file fragmentation you need a defrag tool that also consolidates the maximum amount of free space. If the file system can find contiguous free space it will write files in one piece.

So, if you start to really look at what constitutes the best defrag software you want something that defragments all your files and consolidates the maximum amount of free space. But is there more to look for in a disk defrag program?

The location of the files can also make a difference. Files that don't change often can be defragged and placed together. The next time the defragger runs these files don't have to be moved. The same goes for frequently changing files, they can be located near the free space so they can grow in the fewest number of pieces. Boot files can be placed next to the Master Boot Record for faster system boot ups, and you can defrag system files, the ones Windows 7 doesn't touch, to get them out of the way so your on line defrag is faster.

Combine all of this with flexible scheduling, automatic defragmentation, a duplicate file finder, virtual system support and ease of use and you have something that really qualifies as the best defragmentation software. This is why PerfectDisk 10 is the choice of thousands. These users know that the best defragmentation software does the whole job.

                                             

One way PerfectDisk stands out is its ability to defragment all system files (including all NTFS metadata). System files are 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).                          
                                               
Depending on whether or not the drive is a system drive, or some other drive that PerfectDisk can’t lock, offline file defragmentation may or may not run on the drive(s). 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 a whole or in part — attempts to defragment system files at runtime will usually fail.

These files are then defragmented if the drive is not locked. Otherwise, this occurs at boot time. PerfectDisk locks the drive for its own exclusive use, so it can then defragment and move files the operating system would otherwise not allow to be altered. So, a boot time defrag is really only mandatory for drives that cannot be locked at run time.

                                             
Occassionally when you schedule a boot time defrag pass in PerfectDisk, it doesn’t work. This is because PerfectDisk is unable to lock the drives during boot time, so the system gets booted without the defrag pass getting executed. When this happens, it is almost always because a third-party program has modified the BootExecute registry key so that PDBoot.exe (the name of the PerfectDisk boot time defragmentation executable file) is no longer the first entry in its value string. This entry must occur first in that key for boot time defrag to run correctly. Another possibility is that a third-party software product has opened the drive for write access before PDBoot.exe can mount the drive for exclusive access. If the drive is open for write access, PerfectDisk will not run a boot time/offline defrag in order to avoid potential damage to or corruption of system files.

All system files…to complete the drive and boot quicker.

                                                 

You get what you pay for. And sometimes paying nothing is good enough, sometimes it's not. If you're looking for defrag downloads, you can find some free stuff. That might be okay for you...but maybe not.

Writing in his Naples News Technobuddy column, Bill Husted writes often about free software programs that do a great job. Indeed, he writes that "one of the things I enjoy most with this column is recommending free programs that do a great job. From an early age I’ve been a great believer in the “if it’s free, it’s for me,” school of thought."

                                             

However, Husted goes on to write that "there are programs I do buy. That’s what we’ll talk about today, those rare programs so good that I’m willing to pay for them." As for the Windows built-in defragger, Husted says "it works OK. Perfect Disk 10 is better — so much better that I am willing to pay $40 for Perfect Disk 10 Professional." And the bottom line for Husted -- "my computer runs faster because of it." 

Most Windows defrag software, including the free stuff, won't defrag metadata completely. Won't defrag system files completely. Won't optimize your drives, won't do a good job of consolidating free space...won't do much more than basic defrag of files. A disk defragmentation tool can do a whole lot more, and benefit users a whole lot more.
