ekAEsine: Sorry about my ignorance. I thought files and folders were the same thing.
That notwithstanding, when I unchecked use simple sharing mode I should have had new options when I went to the folder I want to share. I've seen someone else do this and it worked, too. When I do it in this case, (right click the folder, select Sharing and Security) the options are the same as they were.
I bought this computer myself and verified that I am the administrator. I even rebooted and went back to Folder Options to verify that Simple Sharing Mode is still unchecked. Is there another setting somewhere that could be preventing the folders from going into Advanced Sharing Mode?
Frankieee: Thanks. That's a valuable command to know. It'll definitely help me a lot!
