I did something like this once my senior year of high school. I was using XCOPY to copy a copy of Counter Strike: Source that someone had placed on the U:/ drive, but reversed the order of arguments so that instead of copying it to my desktop, I copied everything on my desktop to the directory.

For whatever reason, we had write access to that directory, but not deletion. I had to get the teacher to delete it for me.
