I have asked why Dyson should be. The answer was the folowing:

Dyson is a function that shows DAZ3D which files are used to protect their property and shows the vendors how their files are used.

If you downloaded Dyson as program you will find inside your computer a map called ROAMING, which is to find as followed C: users->> Name>> AppData>> Roaming>>Daz3D>> DysonPoser with a logfile.

Inside the text you will find the shared items which you roam (share) with DAZ3D.

If you downlaod DAZ items today they are called for Poser CF[name] and through Dyson plugin they get readable inside Poser because Dyson is a plugin.

Hope this helps a little to explain what Dyson does. This is probably the meaning that you can't get duf files opened in their new files.
