For reference, I have figured out that you can type in icon type and simply enter the file extension without the '.' or a '*.' in front of it. Just the file extension. Worked for RDP icons. I assume this will work for others as well. I didn't find anything on this and was confused. Hope this helps someone else. Cheers! I can't believe I did not see anything documentation or threads on this as it seems to be a no brainer.

I second this motion! We have a fleet of laptops that use docking bays for dual monitor setups at work, but they are frustrating to deal with when the user complains about this. Only solution so far is to try and use fences on a single screen. I'd like to see a workaround/solution for this. -Qz
Hello everyone, I was googling and searching through the forums and can't seem to find a direct answer. How can I auto-sort my fences by file extension. It seems to only want file names, not extensions. Any help would be appreciated, thank you. -Qz
