How to clear disk space?

I recently started getting a onscreen message saying that a certain drive was almost full and needed cleaning. On my computer I have two user profiles. My personal profile is fine but the one for guests is the one getting the full message. Does this sound familiar to anyone?

Nope. Not familiar to me.
Are you suspicious of Guest Account being infected?
Are there frequent Guest users who may have downloaded large files?

You can simply go have a look:
C:\documents and settings\Guest\local settings\my documents
C:\documents and settings\Guest\local settings\temp
C:\documents and settings\Guest\local settings\temporary internet files

If you're planning to clear out all the junk files on your computer regardless of account:

Clean up your temporary and temporary internet files.

QUOTE
Here's a complete routine to manually do that:
To clean out all the temporary files and cookies on your system.
Go to
Start - Run - (type) "cleanmgr" without the quotes.
Let it scan your system for files to remove.
Check these three boxes and then press ok to remove:
Temporary Files,
Temporary Internet Files,
Recycle Bin.

Then GoTo:
Start - Find/search - Files or folders - in the named box, type: *.tmp
When the list is generated, choose
Edit - select all - File - delete.

Note: If you cannot delete them all at once because you have too many, then click and hold ctrl and highlight a batch of them at a time. Once highlighted, R-click over the highlight and select delete.

Then use
Start - Run - (type) "%temp%" (without the quotes).
Delete the entire contents of that "temp" folder
(use Edit - Select All - press "Delete", click "Yes").

Then,
Empty your Temporary Internet Cache completely.
Close all instances of Outlook and Internet Explorer,
then use "Control Panel - Internet Options - General tab and click the "Delete File" button.
When prompted place a check in: "Delete all offline content", then click OK.

Then, use Windows Explorer to clean out ALL the other temp folders on your system
(navigate to the folder, (as listed below)
use "Edit - Select All", press "Delete", click "Yes"

* C:\Documents and Settings\\Local Settings\Temp\
* C:\Documents and Settings\\Local Settings\Temporary Internet Files\
* C:\Documents and Settings\\Local Settings\Temp\

* C:\Windows\Prefetch\

* Empty your "Recycle Bin".

Note: This is a long manual way to clear out .tmp files. It is safe and highly recommended.

Eventually you may wish to use a "tool" to do this procedure for you on a regular basis.
Download: CleanUp! 4.50 from http://www.stevengould.org
Read about all the options for using this device and use it only after you are satisfied that you understand what it will do for you. I use it regularly, and have a squeaky clean computer as a result. I recommend the default setting that are set during installation.


After doing the above routines, do this separate cleaning of your ActiveX, applets and Java routines:
GoTo:
Control Panel - JAVA - (this will open your JAVA Control Panel)
(in some cases the steps might be Control Panel - JAVA plugins)

Once your JAVA Control Panel is open, you will see a Button down toward the bottom of that panel labeled "Delete Files"
Click - Delete Files - OK, Then close your JAVA Control Panel and Reboot.

Note: The current version of JAVA Runtime Environment is Version 8. If you are running an older version, there are specific "vulnerabilities" that have corrected in Version 8. Recommended: Use Add/Remove to "completely" uninstall your Current JAVA Runtime Environment. Then go to C:\Program Files and Delete the entire Folder of JAVA. Then install the newest version of JAVA Runtime Environment. Get it here:

Please note that in doing the above routines, you will "lose" any auto-login settings that Window has saved for you regarding Websites that you visit that require Username and Password to access the site, and any ActiveX scripts necessary to interact with the Website.

This is not a problem, since you will merely be required to "re-enter" your Username and Password the next time you visit any such site. (for instance, Here at TomCoyote) Or you will be asked to download a fresh copy of any required ActiveX. After that, Windows will again remember the settings for you and you will be able to auto-login again.

It's a good idea to clear up these features on a fairly regular basis, for a couple of reasons. First, ActiveX and applet routines occasionally become corrupted and can be infected with some malwares. Second, temporary internet files are often the first entry point of spyware/malware.

Dough, Thanks for the info.
