Clean out the Temp folder and Temporary Internet Files every so often. (For Temp just put %temp% into a run box and it should pop right up.)

For Temporary Internet Files, it's a bit more complicated. IE can be configured to clear the cache on exit, (which I suggest using) but that doesn't always work, and IE can actually lose track of files that are in there due to crashes. Here's how you can find them:

1. Close all Internet Explorer and Explorer windows.

2. Start type the following into the run box, autocomplete should be helpful some of the time:

C:\Documents and Settings\(your username)\Local Settings\Temporary Internet Files\content.ie5

Yes, that's content.ie5 even though you've probably got IE6. Don't ask me why they did it that way. AutoComplete won't work on the content.ie5 part either because it's normally hidden.

3. You may see a bunch of folders with names made of a random combination of letters and numbers. You can delete those folders. Leave the index.dat and desktop.ini in content.ie5 alone. (You might not see desktop.ini.) If you don't see any folders, and did tell IE to clear the cache at exit, then IE's managed to clean up after itself. When deleting the folder s Explorer will probably ask if you want to delete desktop.ini, you can say yes 'cause that'll be one in the folders you're deleting.
