A user who has permissions to "Rename" a folder can do so as follows:

• Check the address panel to ensure that you are in the folder that you wish to rename.
• Click on File/Rename Folder or the Rename icon on the toolbar.

    

The Rename folder dialog box then appears.  The current folder name will then be editable. 

     

• Edit the folder name in the Rename to field and click Rename.  The folder will then be renamed and the main page will be refreshed.

N.B.  In order to rename a drive, it would have to be re-mapped and all permissions re-set.
