If you place your cursor over 'type' in the screen shot you have shown you should see a drop down arrow.  Click that and it will give you a list of the files to display.

The other way that should work is to use the Organize drop down on the far left of your screen shot and select folder and search options, then view and then about six lines down check the 'show hidden files, folders and drives'.  You might like to change this back afterwards as it can folder list long. 

 

 

I use Poser 13 on Windows 11 - For Scene set up I use a Geekcom A5 -  Ryzen 9 5900HX, with 64 gig ram and 3 TB  storage, mini PC with final rendering done on normal sized desktop using an AMD Ryzen Threadipper 1950X CPU, Corsair Hydro H100i CPU cooler, 3XS EVGA GTX 1080i SC with 11g Ram, 4 X 16gig Corsair DDR4 Ram and a Corsair RM 100 PSU .   The desktop is in a remote location with rendering done via Queue Manager which gives me a clearer desktop and quieter computer room.
