Hi Kumar ,
the below code should help you.
Register the below action for the leaf node for which u need the subfolder's name above it.
Worked fine in my system ...hope it does in ur scenario too
method ONACTIONGET_PATH .
  data : lr_element TYPE REF TO if_wd_context_element,
         lr_node TYPE REF TO if_wd_context_node,
         ls_path type string,
         ls_path_node TYPE string,
         lt_string type TABLE OF string,
         l_lines type i,
         l_lines_1 TYPE i.
  lr_element = wdevent->get_context_element( 'CONTEXT_ELEMENT' ).
**-> getting the path of the node/leaf
*which  u had clicked and from that getting the node above it
  ls_path = lr_element->get_path( ).
  SPLIT ls_path at '.' into table lt_string.
-> remove the first 2 entries as they will contain the view name
  DELETE lt_string FROM 1 to 2.
  l_lines = LINES( lt_String ).
  l_lines_1 = l_lines - 1.
-> remove the last 2 entries as they will contain the element in the path
  DELETE lt_string  from l_lines_1 to l_lines.
  LOOP AT lt_string into ls_path.
    CONCATENATE LINES OF LT_STRING into ls_path_node SEPARATED BY '.'.
  ENDLOOP.
**-> getting access to the node above the leaf element
LR_NODE = WD_CONTEXT->PATH_GET_NODE( path = ls_path_node ).
lr_element = lr_node->get_element( ).
**-> Getting the name of the folder...
*here path is the attribute in my context which stores the name of the folder
lr_element->get_attribute( EXPORTING name = 'PATH' IMPORTING value = ls_path ).
endmethod.
