I've found out how it works in DOpus ...
-
Select the sub-dirs and press CTRL-F (for find/search)
-
In Name Matching enter . (and mark search in sub-folders) and press FIND.
-
The output or find window opens - click CTRL-A to select all
-
Right click the mouse and select 'Copy path+file names as URI' - as long you have added this menu as described here [url]Commands to copy selected filenames to the clipboard]
I've added copy file, copy path+file, copy path+file as URI to my right click menu .. you can add much more so you can use it in the finder/output windows too!
