well i do this post to ask how can erase some of my subdomains or my user account because the ftp of one of my subdomains can not erase some folders and more that I try I can not delete them.

Like me also remove one of my subdomains because I am not using.

Well I hope that I can help to avoid that option do not find any.

And sorry for my bad english is not my first language.

EDIT:

Sorry i forgot it, my account is free, the subdomains are "name.vndv.com"

Well you could have searched for both of these problems.

First, you cannot delete your subdomains or your accounts. Just delete the files off and leave them be.

Second, if you can't delete a file or folder, check the permissions, and also make sure your FTP client is set to show hidden files. Sometimes there are .htaccess files that are hidden in some FTP clients, and therefore won't allow you to delete that folder.

Again you could have searched for both of these answers, please do so next time before posting.
