You can change the name of a folder if you decide that the name does not fit the contents. The name can be any character length up to 256 characters, but blank names, duplicate names, and special reserved characters are not allowed.
Note: A parent folder cannot contain two subfolders with the same name.
Multi-user Considerations
Folders can be renamed in the Library regardless of whether you are working online or offline.
The following rules apply when you are working offline and then return to online status: if the renamed folder or parent folder is marked for deletion, the folder or parent will be restored; if the parent folder has been renamed/moved, the renamed folder moves to the new location; if the renamed folder has been purged, the folder will be deleted; if another author also renames the folder, the last rename is used.
To rename a folder in the Library:
After selecting a document, you can also click the document name or press F2 to start edit mode.
You can also right-click a document and choose Rename.
You can also click anywhere outside the name to save your changes.
