There is a unique RPL instruction to delete both files and directories. Directories must be empty to be deletable.
'output.txt' PURGE
'docs' PURGE
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.

RemoveFile removes a file of any type unless it is a directory that is not empty. RemoveTree remove a file of any type inclusive a directory tree. Note that removeFile and removeTree fail with the exception [http://seed7.sourceforge.net/manual/errors.htm#FILE_ERROR FILE_ERROR] when the file does not exist.
