Recover FTP addressbook from system backup

I was forced to do a full re-installation of my laptop. During the process I lost my FTP address book. I did manage to make a full backup of my old laptop ( I do that on a regular basis), and have access to all my original files.
Problem is that I do not have a recent export file of my FTP addressbook.
Can I copy the addressbook from my last system backup? If so, where can I find the FTP addressbook files?
Thanks for the asssistance.

These two files have your FTP Address Book and default settings.

Before copying any config files manually, I recommend fully exiting Opus (via File / Exit Directory Opus) and then copying them using Explorer.

  • C:\Users<username>\AppData\Roaming\GPSoftware\Directory Opus\ConfigFiles\
    • ftp.oxc
    • ftpdef.oxc

That solved my problem.
