Do you have a temp folder?

Do you have a temp folder at the root of your hard drive? If not, why not?
I always create a folder c:\temp on any machine I use. I use it as a scratchpad workspace for creating collections of things to be zipped up to send to someone, or for temporarily storing a download, or whatever. Using tab-completion, c:\temp is a super-quick path to reach in any Windows dialog box or command line. And making a habit like this makes it even quicker.

The key fact about anything in \temp is that it can be deleted without heartache. I don't put anything there if I need to keep it. If I run low on space, I can always empty this folder (not that space issues comeup much on today's huge hard drives...).
