I'm not really sure what you mean, but since edtFTPD is actually a repackaged version of ProFTPD, you can use most of the . You can place any additional directives between the lines marked "CUSTOMSETTINGS BEGIN" and "CUSTOMSETTINGS END". Make sure edtFTPD Manager (i.e. the GUI) is not running when you're editing the file as your changes will be overwritten. It's OK for the edtFTPD service itself to be running.
