A long time ago I found a hidden directory on my file server that some student had created to store their pirated software. This was back in the days of DOS and Novell NetWare.
Turns out you could create files with "illegal" (and invisible) characters in the filename. The standard OS utilities would not allow them, but the underlying file system did not care. So you could write a short program to do it.

I had to write a utility just to delete it.
