How to Clean Up Your Hard Drive
These instructions have been regularly updated to include new operating
systems, but the basic instructions are the same. They are followed by major
software support firms that have clients whose names you'll recognize, no
matter who you are. So, if they're good enough for the big guys, they'll work
fine for you too. We first made these instructions available through an
auto-reply email about five years ago, but it became overwhelming.
The purpose of these steps is to keep your hard drive clean and error free.
They're particularly helpful if you're printing something in Times New Roman and
it comes out Arial—in all your programs. Or perhaps
your machine is just acting slow and kludgy. It doesn't matter if your computer
is a few years old, these steps can be useful to everyone.
This is probably the most important information you can
have about your computer. Unfortunately, the computer manufacturers won't tell
you and Windows doesn't tell you. There are now features in Windows XP that will
take care of SOME of these steps, but not all of them; these steps are slightly

software that can often cause even more problems, so we encourage distribution

In addition to the instructions below, it is imperative that you run
virus-checking software and update the data files the moment new ones become
available. Running spycheckers, such as
Ad-Aware, is also a

companies have special setups and following these directions could cause
Before starting, shut down your PC and restart it. It is not necessary to log
into your network to perform these steps. When your PC has completely restarted,
close any programs that run automatically, such as Outlook or Yahoo Instant
Hit Ctrl-Alt-Del and choose your Task List. End Task on everything that
appears EXCEPT Explorer and Systray. Make sure nothing is listed in the
Applications tab. Go to the Processes tab and End Task on any items you
recognize, such as RealPlayer, Reminders, etc.
Temporarily disable your screensaver if you use one.
Step 1: Delete trashy hard drive files (commonly referred to as temp files).
or Folders. (Use StartàFindàFiles
or Folders on Windows 98 and 95.)
In the Named box, type:
You must type it exactly as it appears above—double-check
it to make sure it is exactly right. There are NO spaces between any of the
NOTE: There may be programs that actually use these file
extensions, though I've never been told which ones they are. It's unlikely that
you will have a problem.
The Look-In box should have (C:) in it (or other hard drive[s]). You must be
including subfolders in your search.
Hit Search (or Find Now).
When it has completed searching, hit Ctrl+A to select all of the files that
appear, and hit your delete key (see Note below). Delete all files you possibly
can, even if you get a warning. Certain programs will not allow you to delete
certain files. Do not be concerned if you can't delete files, just delete all
that you can, even if you have to delete them one by one. Send all the files to
the recycle bin. Close the Search window when you’re all done.
NOTE: For some reason, Windows 2000 stores certain folders
in the TEMP folder. You should not delete these folders. When you choose to
delete the files, you are told that it "is a system folder". You should not
delete system files or folders.
Step 2: Delete Windows temp files.
Hit Start-Run and type %temp% and hit enter.
NOTE: The TEMP folder is a system folder. Do not use these
folders to store your own files. Do not allow files to be stored here
The contents of the Temp folder that your system uses by default should
appear in the window. Hit Ctrl+A on the keyboard to select everything in that
folder and hit your delete key. Send the files to the recycle bin. Leave them
there for at least a week to ensure that none of the files were needed. However,
Close Windows Explorer.
Step 3: Delete temporary Internet files.
These steps valid only with Internet Explorer users.
Open My Computer and note the Free space on your local drive by hitting ViewàDetails.
Now calculate a quantity of perhaps 10% of the amount of space available on your
hard drive. Close My Computer.
Open Internet Explorer and hit ToolsàInternet
Options. If you are having difficulty running Internet Explorer, right-click the
shortcut and hit Properties to bring up the Internet Options dialog.
On the General tab, click on the Settings button. Set the amount of disk
space for Internet Explorer to use to the amount that is equal to 10% of your
hard drive space. This is just a rule of thumb and is not necessarily
appropriate for everyone.
If you’ve got DSL or Cable, check the box “every visit to a page". If you’ve
got phone-line internet (DUN), check the box “every visit to a page" and groan
while you do it. There’s no point in going to web sites and NOT viewing the most
updated page. If you want to see the old page, then add it to your favorites and
tell it you want it to be available offline.
Click on the Delete files button. Do NOT click the checkbox for “delete all
The history section has 20 days by default. Another rule of thumb—3
days ought to be enough. If you disagree, then you certainly know more about
your Internet habits than I do.
Click on the Advanced tab. Scroll down to the Security area and check the box
that says “empty temporary internet files when browser is closed". This keeps
them from building up and taking all the space on your hard drive.
Close any and all open Windows.
Step 4: Cleanup by running Scandisk and Defrag.
Ideally, at this point, you’ll empty your recycle bin. The first few times
you perform these steps, however, you may not want to empty your recycle bin.
Give it a week or so. When it's obvious that you did not delete anything
important, empty your recycle bin.
NOTE: Some operating systems don't have Scandisk. If yours
does not, you don’t have to run scandisk or defrag, you just need to reboot your
PC and you’re done. Check for Scandisk by double-clicking My Computer, then
right-click your hard drive and choose Properties. Then click on the Tools tab.
You may find Error Checking (Scandisk) there. Choose Error Checking. You may be
advised that you'll have to run it after restarting your PC. Do so. Be warned it
may take a half hour or more to run it when you've booted your PC.
Double-click My Computer, then right-click the C drive (or your hard drive)
and choose hit Properties, then Tools. Hit the Check Now button. Likely, you'll
be told that it will run next time you restart your machine, say OK and restart
your PC now.
NOTE: In older versions of Windows, you need to hit StartàProgramsàAccessoriesàSystem
toolsàScandisk. Run it on the C: drive, choose
Standard test, and choose to Automatically fix errors. Hit Start.
When Scandisk has completed, it will tell you whether it found problems or
NOTE: On pre-Windows XP PCs, scandisk can also be run by
restarting the computer in MS-DOS mode and typing “scandisk" at the DOS prompt
and hitting enter. This is particularly useful if you get the message “Scandisk
has restarted 10 times."
If you're using these steps to troubleshoot a specific problem, you can skip
the next step, but you should definitely do it as soon as you can.
Hit Start-Programs-Accessories-System tools-Disk Defragmenter. Run it on the
C: drive whether it needs it or not. If you have never run Defrag before, or if
you have not run it in a long time, this could take hours! When it’s done,
hit the Yes button to exit the disk defragmenter, and restart your PC.
NOTE: Some operating systems don't have Disk Defragmenter.
Check for Defrag by double-clicking My Computer, then right-click your hard
drive and choose Properties. Then click on the Tools tab. You may find Disk
