Get Size (Byte) Of Directory VB6

Berikut ini adalah cara mengetahui ukuran (size) suatu direktori dalam hitungan bytes di visual basic 6, untuk mempraktekannya siapkan :

1. Buat 1 Project baru dengan 1 Form, 1 Module, dan 1 Commandbutton.
2. Copy-kan coding berikut ke editor form yang bertalian.

          '--- Coding ini di Module...
          Public Const MAX_PATH = 260
          Public Type FILETIME
            dwLowDateTime As Long

            dwHighDateTime As Long
          End Type

          Public Type WIN32_FIND_DATA

            dwFileAttributes As Long
            ftCreationTime As FILETIME
            ftLastAccessTime As FILETIME
            ftLastWriteTime As FILETIME
            nFileSizeHigh As Long

            nFileSizeLow As Long
            dwReserved0 As Long
            dwReserved1 As Long
            cFileName As String * MAX_PATH

            cAlternate As String * 14
          End Type

          Declare Function FindFirstFile Lib "kernel32" _
             Alias "FindFirstFileA" (ByVal lpFileName As String, _
             lpFindFileData As WIN32_FIND_DATA) As Long
           
          Declare Function FindNextFile Lib "kernel32" _

          End Function

          Private Sub Command1_Click()
            'Ganti 'C:\Windows' di bawah dengan nama direktori
            'yang ingin Anda ketahui ukurannya.
            MsgBox "Ukuran direktori C:\Windows = " _

                   & Format(SizeOf("C:\Windows"), "#,#") & " bytes", _
                   vbInformation, "Ukuran Direktori"
