There is a unique RPL instruction to delete both files and directories. Directories must be empty to be deletable.

HOME output.txt' PURGE
HOME 'docs' PURGE
Basically, <code>HOME</code> moves the user from the current directory to the root. If the last two commands are done successively, only the first call is necessary.
