Defragmentation and Compaction of Fragmented Files Easy, for each day, just try to analyze all your drives. From the scan results, you can determine when to stat defragmentation. Obviously, if there is a bit of red lines (fragmented files), you got to do the defragmentation process. Hopefully, you got another working computer around because defragmentation takes a while (from a few hours to a few days). Some people online say that one defragmentation per week will do, but I say it depends on how much files you mess around with. I leave that up to you. During the scan, if you see that the Disk Defragmenter is defragmentating compacting files, well, you have finished defragmenting (there might be a few red lines left so you might want to defragment again), but you can leave the scan alone to wrap it up. If you see any blue (contiguous) and green (unmovable) lines, then those lines ought to be left alone. You can keep defragmenting to try removing all the blue lines, but I doubt it's something that can be removed nor is considered a computer problem. Oh yeah, don't defragment daily, it might cause hard drive problems in the future. To access the Disk Defragmenter, access the Start taskbar, right-click on the My Computer icon, left-click on the Manage sub-options, and left-click on the Disk Defragmenter sub-option. There are other methods to access the Disk Defragmentater, but the instructions above is the most common. I am probably missing other methods to clean up computer virtual space, but it would be in the future (got to figure out how to avoid the Disk Clean analysis scan [such a waste of time]). Now there are those people who want to throw their money away from their living expenses for the solid drive devices. All I can say is that I rather stick to the cost coefficients and cater to what been running, living, and breathing. The lowest denominator is good enough for me and probably for most people in the world.
