Smart Group on file extension - how?

I use Prism for data graphing. It creates files with a .pzf extension. I want to be able to group all .pzf files in a smart group. How do I do this?

Tells me all I need to know. Thanks.

Don’t know if you’re second post meant you found the answer or that the lack of replies “tells you all you need to know.” :confused:

Regardless, and easy way, if you don’t run the script to remove extensions, is to set the smart group up to search for Name and matches .pzf

That should pull all of the files with the extension, unless you have removed the extension as noted above.
