Empty folder

How can I know if a directory is empty (without files)?

Somebody know a function? or have any idea?

Thanks a lot.

You can use this FM: TMP_GUI_DIRECTORY_LIST_FILES

Like:

  DATA: TBL_FILES LIKE SDOKPATH OCCURS 10 WITH HEADER LINE,
        TBL_DIRS LIKE SDOKPATH OCCURS 10 WITH HEADER LINE.


  CALL FUNCTION 'TMP_GUI_DIRECTORY_LIST_FILES'
       EXPORTING
            DIRECTORY  = P_DIRECTORY
       TABLES
            FILE_TABLE = TBL_FILES
            DIR_TABLE  = TBL_DIRS.


describe table tbl_Files lines sy-index.
if sy-index is initial.
*  no files in the directory
endif.

Thanks a lot .

I decided to use a class.

CALL METHOD CL_GUI_FRONTEND_SERVICES=>DIRECTORY_LIST_FILES
    EXPORTING
      DIRECTORY                   = 'C:HELLO'
*    FILTER                      = '*.*'
*    FILES_ONLY                  =
*    DIRECTORIES_ONLY            =
    CHANGING
      FILE_TABLE                  =  LV_FILES
      COUNT                       = SIZE
*  EXCEPTIONS
*    CNTL_ERROR                  = 1
*    DIRECTORY_LIST_FILES_FAILED = 2
*    WRONG_PARAMETER             = 3
*    ERROR_NO_GUI                = 4
*    NOT_SUPPORTED_BY_GUI        = 5
*    OTHERS                      = 6
          .
  IF SIZE IS INITIAL.
    MESSAGE 'La carpeta de entrada está vacia' TYPE 'I'.
    LEAVE PROGRAM.
  ENDIF.
