That is, when you create a new folder within a folder, the newly created folder is created within that folder. This makes it easier to organize your worksheets and allows you to set up your folder system in the most transparent way possible. The navigation button at the top left shows you the folder you are currently in. This button is clickable, so you can click the name at any time to go back to another level. For example, if you have a folder within a folder and there are subfolders associated with it, you don't have to go back to the desktop one step at a time. Just use the navigation button and click Desktop to go back here.
