Different icon for .3dm file

Hi guys,

Question: as my plugin writes directly to .3dm file - I would like that user recognizes if .3dm file contains plugin data by only looking at the icon and not loading it. Let’s say - smth similar as Dropbox does placing a small sign at the corner of the file icon.

How to arrange this?


You’ll have to write a shell extension that essentially reads the file, and adds an icon overlay when deemed necessary.
