A well known computer maintenance task is to defragment your hard drive periodically. Two things about defragmenting hard drives aren’t known.

#1_Open files don’t defragment while the defragmenter is running.

#2_If you defragment your hard drive while in “Safe Mode” (press F8 at boot time) only a certain amount of drivers are loaded, files that are open while you are in your “User Account” are extremely limited to run in safe mode. The ending results of defragmenting in safe mode, nearly all files on the hard drive are defragmented. If you use “Windows Defragmenter” first, while in safe mode some files may not defrag,(example;anti-virus program files) so run the “Defraggler Program version 2.15.742” (100% Free) -portable option- offered by

Once defraggler is up and running, click the option analyze. After analysis is complete, choose defrag files that defraggler found -they didn’t defrag-. However; secure data that you may have locked in a vault, ie; “My Lockbox”, may not defrag. If you want to defrag that data as well, unlock them before defragment begins (unlocking secure data may have to be done while in your user account). Remember your in safe mode, no need to be concerned about unlocking your private data (unless you have chosen to go into safe mode with networking).

I suggest safe mode without network.

This maintenance task works on all “Windows OS’s” machines.

Every time I need to defragment I do so in this manner and have found that optimization of my hard drive is 100% better than if I defrag while in my user account. Give it a try -it won’t hurt a bit- sounds like a lot to do, its not, just a little task and defrag time (depending on the capacity of your hard drive).

NOTE: the purpose of running “Windows Defrag Utility” first is_”compacting files”.
And its still rated to be the best defragmenter…
