Ok, yes that worked. I had to wait a long time for it to open, maybe that's why I thought that wasn't working that way when I tried it. Thanks for the tip.

I'm having the same exact issue on Windows 10 I create the gallery works great on my site, but when I need to edit it i.e. update it the cofig xml file does not show in my folder. It shows if i navigate via my windows folders, but not if I'm going to open the file to open the gallery. Very frustrated with this.
