How defragmentation works for the computers?
343412
Refers to the condition of a disk in which files are divided into pieces scattered around the disk. Fragmentation occurs naturally when you use a disk frequently, creating, deleting, and modifying files. At some point, the operating system needs to store parts of a file in noncontiguous clusters. This is entirely invisible to users, but it can slow down the speed at which data is accessed because the disk drive must search through different parts of the disk to put together a single file. \nIt wont remove any of the installed programes in your system. It just rearrange the data in a specific order.\nIt is no way same to Formatting.

Are you running other programs while you defrag?  If you haven't done it for a long long time, it can take up to a day or so...but you're right. That does sound awfully slow.\n\nI'd try freeing up as much space on your hard drive as you can, deleting temporary files and the like, then restarting and running the degrag program by itself.\n\nOh, and also, sometimes anti-virus programs running in the background can screw with it. Good luck.

go to start, accessories, system tools, and it should have disk defragmentation.

For XP users, open My Computer and right click on (C:).  Goto Properties then Tools and click Defragment Now

Defragmentation is the process a computer goes through to put the files and folders and programs in order. A lot like a desk or filing system, if things are placed in a sensible order, you are able to find things faster and complete projects easier. The computer needs this too. \n\nLast told, an average user should probably do this once a month. But if you add and remove files frequently, then doing it once a week will speed up your computer just a bit.

Try defraging the hard drive. Click on start-click programs-scroll to accessories,system tools then click on disk defragmenter. While in the program click on analyze it will probably tell you it doesn't need defraging but defrag it anyway.

if you use your computer a lot, your files may be fragmented. do a weekly defragmentation.

Once in a month. Moreover u should defrag only when u r recommended to do that. Before defraging, u should analyze the drives.

On a windows computer, hit start, then programs, then accessories, then system tools, and there should be "Disk Defragmenter." Start up that program, and follow the instructions.\n\nYou should defrag your computer every few months to keep it working at top speed.

do defragmentation, go to control panel and select performance and maintenance.

The first answer was good advice, but you could also try to defagment your hard drive.\n\nto My computer right click on your hard drive go to properties, click on disck cleanup and defragment.\n\nGOOD LUCK!

Imagine a filing cabinet where when people take files out, they never put them back in the right place.  After a while it would get hard to find the files.  Your hard drive is simiar to this and defragmenting is like organizing your file cabinent in order for your computer to find the files more easily.  There are no disadvantages, and you should do this at least once a month, maybe more with heavy usage.

I would re-boot the computer and try it again. Also, do you have your defrag set so that it will do it at a certain scheduled time? That would help, also, because then, you wouldn't have to manually do it. You just need to program it in your scheduled tasks, which you can access from your control panel.

Go to the Control Panel option on your start menu and choose performance and maintenance.  There should be an option for freeing up space on your hard drive.  It is call defragmenting, and does not remove programs or file.  It only rearranges them to make them more organized and take up less space.

well since cookies seem to be explained well enough, on to defraging. When you save files to your hard drive, they don't always save all together/contiguously. There will be parts of it here, parts of it there, etc. So, this will slw down your hard drive, because when you go to open that file agian, the computer has to go and find all the parts. So, if you defrag, it puts all the "fragmented" peices toghther, so that they are contiguous. Hope this helps. By the way, defraging will make your computer go faster, and its good for it.

Defragmentation doesn't have anything to do with moving parts. When you write a file on a hard drive (or other Rewritable device) sometimes there is not enough space to put all the file in one piece so the file is cut in small parts and we say the file has been fragmented.\n\nWhen you defragment a device you put back files all together in one piece, this allows your system to read faster cause you don't have to search for different pieces all over the device.\n\nOn a USB flash drive the space is rather small so even searching through the memory isn't wasting too much time so I'd say you don't really need to defragment it but it's something you can do. \nIf one day USB flash drives become very big (around 5Go is the limit I think) you may come to defragment them.

Simply, when you install and delete programs and files, you create blank spaces in the hard drive.  Programs that are installed are placed in available spaces, not contiguously. which can cause the hard drive to work harder, and slower.\n\nDefragmenting the hard drive takes all your files and programs and puts them back together so the hard drive can work faster and more efficiently.\n\nYou can run a defrag every couple of months, or specifically when you want to install or have just deleted a big program.
