Move Resources
As in the case of the copy command, you can move several resources at once. Select the resources in the Working Copy view and choose the Move to action from the contextual menu. The move command actually behaves as if a copy followed by a delete command were issued. You will find the moved resources at the desired destination and also at their original location, but marked as deleted.
Note
External
                  items cannot be moved using the Move to action, because they cannot
                  be deleted. Instead, you should edit the 
            svn:externals property defining the
                  external item and 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.
