Do you delete your zip/rar files after you extract them?

I have this funny habit of keeping the zip files on my comp even after I extract them and view all the files and pics in them and knowing that I dont need the zip file anymore. I guess these zip files will slowly start clogging my hard disk. What do you do after extracting and seeing all the files that are in zip or rar files?
