I've had an iPhone for a couple years now and am pretty familiar with that, but am new to the desktop interface. I am trying to put sample files into folders as part of a class project. However, no matter how I select the folder, it always puts the item in the highest directory. For example, I am trying to put a new folder on my disk called 13 colonies in my CTEC103 folder on my USB drive. I press command shift N for new folder while the VoiceOver cursor is on the CTEC103 folder, and it creates the new folder, but that folder is one of the many on my disk, not inside the CTEC103 folder where I want it to be. How do I do this?
