In order to delete a folder, you must have "Delete" permissions.  The folder must also contain no files.  If so, proceed as follows:

• Ensure that the folder that you wish to delete is the current folder i.e. the folder that is in the address panel. 

• Click on the Delete icon on the toolbar.

The Delete folder dialog box then appears. 

     

• Click Delete.  The folder will then be deleted and the main page will be refreshed.
