What are the correct temporary files to delete to make my computer run better?

by on February 26, 2009

Q: Everything you do on a computer is saved on the hard drive, even if you delete it, there is still a part of it left in the hard drive. How can you go into the hard drive and delete all of the temporary internet files and all the other files. No matter how much I delete files, my computer speed doesn’t improve, load increases. When my dad gives the computer to somebody that knows this stuff, they find all kinds of files and then the computer gets better and all junk files are gone. How can a normal person delete all of these junk files in the hard drive? Please tell me the procedure to go in the system files and delete all of this junk.

    – Uninstall any programs you’re not using
    – Try using http://www.ccleaner.com to get rid of temp files and other junk
    – Run windows defrag

    If you are using Microsoft Windows, the easiest way to run the maintenance you’re seeking is using automated tools. I recommend the following FREE programs:


    Run both tool with all options selected in CCleaner. Defraggler is better than Windows’ built-in defragmentation tool. Recuva is optional; it allows you to both securely delete files and recover accidentally deleted files.

    Finally, go My Computer => right-click on hard drive => Properties => Tools => Error-checking => choose both checkboxes => schedule the error-check for the next time you start your computer => restart your computer. Repeat this for all hard drives in your computer.

    Due to the ancient design of ALL versions of Microsoft Windows, even the best maintenance programs will eventually become ineffective on your computer. When this happens, your only option is to reinstall Microsoft Windows.

    PS: Operating systems such as Mac OS X and Ubuntu Linux require less maintenance and are less susceptible to viruses, malware, etc than Microsoft Windows.

    You can either run diskcleanup or download and run CCleaner. It gives you the options to select what files you want to delete. You can normally delete temp files, temp internet files, recyclebin files etc.
    After running a diskcleanup be sure to run a defrag as addition and deletion of files leads to fragmentation of the drive. The built in defragger needs 15% free space on the volume to defrag. I recommend you download and set Diskeeper in automatic mode. It defrags thoroughly even under low free space.


    Jayanth presents some good ideas. Running Disk Cleanup is an excellent suggestion, as it removes a couple of items from your computer that CCleaner might miss. You can run Disk Cleanup by going Start Menu => My Computer (called Computer in Windows Vista) => right-click on your computer’s main hard drive (usually called C) => Properties => Disk Cleanup. In Windows Vista, you should choose all options in the Cleanup tab. IMPORTANT: In Windows XP, you will see an option in Disk Cleanup called “Compress old files”. DO NOT select the compress option, as running that option will actually cause your computer to run more slowly!

    I recommend trying Defraggler (free) before resorting to Diskeeper (costs money).
