Delete created directory

Created few directories using below short codes. The created folders can be seen under specified path using FTP.

[fileup sub=”facebook” showto=”administrator” makedir=”true”]
[fileup sub=”google” showto=”administrator” makedir=”true”]
[fileup sub=”twitter” showto=”administrator” makedir=”true”]

Is it possible to delete a directory(folder) without using FTP ?
How could I delete directory ‘facebook’ for above shortcode ?
