Thank you for your answer.
I installed the latest version 3 days ago (ver. 22.214.171.124).
I tried to check with my downloads folder and with a dropbox folder, and even with new folder which I created just for this on my desktop.
The wired thing is that I tried it on 3 different PC's, one at my home, one at my office an on my Surface 7 pro. It doesn't work on any of them.
Just to let you know, I'm in my 30 days trial version.
Hope you can solve this matter for my, because this is the main purpose which got me to install Fences in the first place.
