What is disk defragmentation?
967863
The storage section of any computer is divided into tiny portions called tracks and sectors.The files that we save are actually fragmented into various portions before they are saved on the hard disk in random sectors. So, when you want to open a file, the Operating System collects the fragments from various places, joins them and then shows it to you. By computer's means, this consumes a lot of time(usually over 100 milliseconds). However, if the disk is defragmented, the OS brings all the fragments of different files together, thereby pushing the used up space to one portion and the free space to another. This helps the computer in retrieving information much faster and hence your computer 'speeds' up! Hope you got it! :-)

You need to open your start menu, then go on Programs, Accessories, System Tools, then on Disk Defragmenter.

Do a regular disk defragment (this is like doing filing within your comp - puts files back in place) from "all programmes>system tools>defragment".  Install a programme like cccleaner (a free download), this cleans everything from temp files, memory dumps, MRU lists and a tonne of stuff.  AVG FREE antivirus is great.  Make sure your Firewall is turned on through your Security centre in the control panel...if you run all these programmmes on a regular basis it should keep things running smoothly, alternatively upgrade your memory as the fuller it becomes the slower things will get.  Hope this helps :)

There's a brilliant program called Ccleaner. I use it so it must be idiot proof.\nwww.ccleaner.com\nDefragment the hard drive, go to Start - Accessories - System Tools - Defragment.\nAlso, try storing big files like images on a separate partition, or preferably a separate drive such as an external hard drive. Pc's do slow down as you start to use them and I think to an extent its unavoidable.

Defragging,\nOne should do a  disk cleanup everyday and defrag two or three times a week if the computer is used moderately. Try this. \nYou may need to do a Disk Cleanup..and be sure you have all the boxes checked.... \nDefrafg your C drive or what ever is your \nmain harddrive... Make sure you have selected the C Drive.... This is called a Disk Defragmenter... \nGo to : Start... \nprograms.. \naccessories... \nsystem tools..\nDo this often... \nRemove all that is Not necessary from the start up.  Go to... \nStart \nRun\nType in .. msconfig\nin the general tab.. choose selective start\nthen choose the start up tab\nand remove all that you dont need.  \nE

Start here\nOne should do a  disk cleanup everyday and defrag two or three times a week if the computer is used moderately. \n1.  You may need to do a Disk Cleanup..and be sure you have all the boxes checked.... \n2.  Defrafg your C drive or whatever is your main harddrive... Make sure you have selected the C Drive.... This is called a Disk Defragmenter... \nFor both go to : \nStart... \nprograms.. \naccessories... \nsystem tools..\nDo this often... \n3.  Then go to your.. My Documents... Or wherever you keep you personal documents.  Right click on each folder, select properties and see what size they are.  When you add them up you might find that KBs turn into MBs and they turn into GBs real fast.  So you may need to delete what you dont want and burn what you want to CDs.  Music, Videos, High quality photos take up tons of space. \n4.  Some software can take up to 1/2 Gig or more of space.  Go through your old software and remove any you are not using.  Including any software products that may have come with your computer that you are not using.  Check through your ..Add or remove programs in the control panel.  I hope this helps some. \nGood Luck\nE

All defragmenters do the same thing: they move files' clusters to use contiguous disk space and thus reduce the time of disk access when reading some file. No one is better than others.

Let's say that you want to delete ALL of the files in your MY DOCUMENTS folder.    Right click on MY DOCUMENTS and pick EXPLORE.   Click on any file on the RIGHT SIDE and use CONTROL and A (to select all).   Then RIGHT CLICK on the highlighted files and pick DELETE.    All of those files would delete.   Then empty your recycle bin. \n\nBut for programs, open the Control Panel and use the ADD/REMOVE section to uninstall each one.   So at this point, those programs would be safely removed. \n\nIf you are GIVING this computer to someone else, but want it functional, use the DISK CLEANUP program that is in the System Tools of the Accessories section.  Also, take the time to test the disk.   Open My Computer, then Right Click on the C drive and pick PROPERTIES.  Then pick the Tools section.  Click on the CHECK NOW button, check both tests then let the test run after you REBOOT.   \n\nAfter testing the disk, run DEFRAG.  Find this also in the System Tools section.    When you DEFRAG, this will move many files around and connect them together.  During this process, remnants of your old files, even though deleted previously, will be scrambled pretty well.   This will also optimize the system and really make it "as good as it can".\n\nGood luck and Happy Computing!

If you have a very large hard drive and lots of fragmented files on that drive, then it could take a *very long* time to complete defragmentation.\n\nSometimes it is best just to let the defragmenter run overnight instead, it can take several hours in a very bad case of fragmentation.

defrag and do a disk cleanup

Keep in mind that defraging the IS .edb file is NOT going to defrag the IS internally.  On a properly designed system, the IS is on a drive (or partition) by itself, so fragmentation should not become a significant issue.\n\nThe temp files are deleted at each backup, so I'd suggest running Diskeeper on a scheduled basis after each backup to keep the .edb and .stm files as tidy as possible.  Do this during off-peak hours.

You probably have programs running in the background that are preventing it from working properly. For Windows, restart into Safe Mode and try running Disk Defragmenter there.
