Using that, you may delete your entire site: don't keep it in your public area !

idea:
on some hosting site you can move the file you want to delete to the /tmp dir. from there they will be deleted at some point. at least this is an easy way to move stuff out of your quota.

Note: Depending on how the hosting is setup /tmp might in fact be within your quota and your home area, dont rely on this method. - Damian
