Pure-FTPd Password Change

I have the Drobo FS and Pure-FTPd software on it, I have it working as I want taking Backups from another location. Problem is the USER NAME and PASSWORD is “root”. I want to change both of these but I cannot figure out how !I have Dropbear installed and also Have a peice of software called WINSCP but Im not sure what files I have to access, I have been tryying the passwd file in the etc directory but no luck. Maybe it is the way Im doing it , maybe it is different software I should be using. HELP !!!

Goto droboadmin interface, there under ‘information’ you can find an app and explanation how to do this.
