Can someone please tell me how to programmatically find a sub folder within Root Folder? I'm using RootFolder.FindSubFolder(" ")   but its not working. I don't understand what syntax and what kind of relative path it is asking for.

It can't find an existing sub folder within the root folder. Can somebody please explain how to mention the required path in c#? Folder I want to find is at location like "D:\Lesson Plans\".

 

Any help will be appreciated.
