To create a FTP account for a user, follow these steps:
(a) Login to your control panel
(b) Under the FTP Tab (near bottom right section)
(c) Click "FTP Accounts"
(d) Click "Add Account"
(e) For the login field, enter any name you want
(f) Enter a password
(g) Click "Create”
The login name will become the created directory. If you entered "joe", a directory called "joe" will be created under your "public_ftp" directory. If you already have a directory called "joe" then a new directory will not be created. To login to your FTP accounts use the following settings in your FTP software.
Users will only have access to the directory you create. If you create a login name called "joe", then once logged in, joe can only access the "joe" directory and anything below that e.g. yourdomain.com/joe/test/. Joe will not be able to access any directory higher than his directory.
