I'm still not in bed.

There is a folder. Inside this folder is a huge collection of temporary subfolders, copies of files that I downloaded years ago, and various other seemingly useless 0-byte files with meaningless alphanumeric names. The folder is "Temp", and it is hidden away in Local Settings. Currently it is taking up 1.19GB of my hard disk space.

Working on the theory that it's better to ask and be a fool for a couple of minutes than not ask and be a fool for ruining my computer - can I delete this junk? The name of the folder (and my computer science sense) suggests that it's just leftover stuff from various things that were never deleted for one reason or another - that or an incredibly bloated cache - but is it remotely possible that Windows XP is using anything in there?
