I thought Photo Mechanic 6 had this feature already, but now I can't find it.
What I need is a way to hide files created by Capture One, because my PM displays a lot of thumbnails for *.cos, *.cof and *.cop files. When using RAW+JPG, I'm seeing six "useless" thumbnails for every picture.
I hope that I have overlooked this feature, but if I'm not, please make a way to hide irrelevant content.
Try unchecking Unknown Files as Proxies in the View menu and see if that works.
