Sketchup Material file .skm support

[Mr-Black]

Hi all I know Xnview can view .skp files but could you do the same with sketchups material file .skm

It would be a nightmare trying to sort through them blind, although some of the .skm files display a thumbnail many don't even though when I extract the file using Keka a thumbnail exist, so this looks like a zip file with a .skm extension.

This is the files structure...


Is it possible?
