selecting DNGs only in contact sheet or catalog view

[braver]

I'd like to be able to select only DNGs in a contact sheet.  Currenly I can sort by type and then manually select the range of DNGs.  But I'd like to do that automatically, how?  I vaguely remembered using tagging for this but then I'd need to tag by type.  ChatGPT keeps proposing I use a filter view in PMP but there's no such thing for the contact sheet view!

I tried to do it in catalog, selecting a folder path from browse and hoping to apply a filter by DNG type.  However filter shows al DNGs in the catalog.  Is there a way to combune a filter with a path?

Also, why does Edit=>Select RAW Photos is greyed out when I only have JPGs and DNGs?  I convert all RAWs to DNGs but Leica and Pentax write our DNGs by default.  So I'd like that option to work for DNGs.

Bump -- am I missing something?  Surely there should be a simple way to select all DNG files in a contact sheet without eyeing each one/sorting and eyeing the range?

One way you could do this is to use Find (cmd-f on macOS, ctrl-f on Win)

Running Find with .dng in the field and checking the box for Filename would select all the .dng files in the current contact sheet.  You have the option of checking a box so that the contact sheet automatically filters after running the find to then only show selected files.   You can also create a snapshot preset (for .dng or other filetypes) with your chosen options to minimize typing/options each time

This example shows me finding .psds, but the idea is the same.

I hope this is possibly helpful.
