Problem in public_html

[gavonlineweb25]

Hi,
I had earlier installed Joomla using fantastico and then uninstalled it ( as I included sampled data by mistake -which I did'nt want ) . Anyways after uninstalling . I still have a lot of the joomla directories which I'm unable to delete . I've tried deleting from Cp as well as from my ftp client ( I use Bulletproof) . But the Joomla folders wont go , making it difficult to reinstall Joomla .
Is there anyway of Clearing all my Folders in public_html ?

Could you please post your domain name ?

Try setting the permissions of public_html to 0777 , removing the files and folders, and then returning the permissions of public_html to their original settings.
