How do I name a tree/folder after I started it and it is unnamed?

How do I name a tree/folder after I started it and it is unnamed? I made a new tree but missed naming it and now can’t find a way to give it a name in RM9.

To rename an existing database, open it inside RM first then go to File, Tools, Move/Rename. As long as you are inside the same folder it will rename it. If you selected a different folder that is when it moves it. If you are trying to rename the folder the database is in then you need to do that outside of the program. On Windows 11 right click on the folder, select “Show more options” then select Rename.
