I don't think it is. I just created a new folder using IO.Directory.CreateDirectory and then checked its attributes and it wasn't read-only. The read-only attribute was set to indeterminate (the box was filled rather than checked) and it said "(Only applies to files in the folder)". I was then able to open the folder and create a new text file in it that was not read-only. Have you tried to create a file in your new folder? Are you able to?
