I Love Tools Like This: HFS
Why do I like TFTPD32? Because it's so freakin' simple! When you're in a data center and need a quick TFTP server...there it is.
...who knew they had one for HTTP? There it is: HFS - A 600KB "insta-web server" for Windows.
Update: A few malware detection utilities flag this as malware simply because it's a .exe file named HFS. It's completely safe...I've been using it for at least 32 minutes and nothing bad has happened...
