I have a 1815+ and I'd love to test new versions. I'm having trouble figuring how to share a certain folder. Let's say I want to share a folder inside a main folder that's in volume1. //volume1/first folder/second folder. However this is what happens. I click volume1, it opens and I can see first folder, I click on that and it won't drop down with the list of folders with in that one. It said I don't have persmissions, however I'm the admin. Do i have to give some other username access?
