Files and folders in your workspaces can easily be renamed at any time. Administrators, Moderators, and Collaborators have permission to change file and folder names. In addition Creators who created the file or folder can change the name as well.
To get started renaming files and folders, make sure you are in the file list view. Renaming cannot be done from thumbnail view.
Once in list view, just hover your cursor over a file or folder and click the options (⋯) icon that appears in the actions area.
Click the Rename option.
Then simply edit the name and click Update.
