There are several folders that I routinely empty, above and beyond what Mr. K.V. Collucci mentioned. I have a computer running Windows® ME ("Mediocre Edition") so these instructions may not be proper for your particular computer and/or version of Windows®.
Along with the contents of the TEMP folder, I also delete the contents of my "Cookies" folder, the contents of my 'Temporary Internet Files' folder, the contents of my "Recent" folder, and, most importantly, the contents of the folders that are hidden inside your 'Temporary Internet Files' folder's hidden Content.IE5 folder. If you don't remember all of your passwords, for the places that you visit online, I would suggest not emptying the contents of your "Cookies" folder, because those files contain your passwords, encoded.
Sorry, I know that sounds confusing. My Windows® ME computer has a hidden folder located inside the "Temporary Internet Files" folder, named 'Content.IE5' and it can usually best be found using Explorer.exe or Search. Anyway, inside my "Content.IE5" folder there are twelve folders, named with alpha-numeric names (for example: 4FMPOLCX, 4PANK52Z, 8RABUVEF, KH6FWPER etc.), and those folders contain copies of all of the web pages, images, music files, etc. that have been viewed during your Internet surfing.
From the first day you started surfing, if you've never before emptied those hidden folders.
I don't know why Microsoft likes to secretly cache copies of all of one's Internet surfings, but I don't like it, myself. So, I clean those out each time I'm rebooting. My Uncle had about a gigabyte of cached files on his computer, within, IIRC, sixteen of these hidden folders, within the hidden "Content.IE5" folder, within his (and your) 'Temporary Internet Files' folder.'
I hopes that this is more helpful than confusing. If you are uncertain about any of these above instructions, I would suggest that you not attempt them. You can delete the contents of each of the folders that I've mentioned, without damaging your computer, but, I'd call your computer's manufacturer to check and ask, before deleting those folders' contents, on my word, alone.

P.S. I agree with Mr. K.V. Collucci that BladeForums should have a specific Computer Forum. Because, after all, Microsoft created the "three finger salute" of CTRL+ALT+DEL for a reason.
