Rename Resources
The Rename action is available in the contextual menu of the Working Copy view and can be performed on a single resource. This action acts as a move command with the destination directory being the same as the original location of the resource. A copy of the original item is created with the new name, also keeping its history. The original item is marked as deleted.
Note
External items cannot be renamed using the
                  Rename action because they cannot be deleted. Instead, you should
                  edit the svn:externals property defining the external item, then
                  use the Update operation on the item's parent folder for the change
                  to take effect.
               
            Attention
For SVN 1.8 working copies: when
                  committing items that were moved and/or renamed, make sure you select both the source
                  and the
                  destination. Otherwise, the commit operation will fail.
