:directoryExists(string:path)	string[]	Returns whether the given path exists and represents a directory
:delete(string:path)	void	Deletes the specified file or directory. Directories are deleted recursively.
:move(string:srcPath, string:destPath)	void	Moves the specified file or directory to the destination path.
:makeDirection(string:path)	void	Creates a new directory at the specified path.
