XL2000: How to Programmatically Display All Files in a Folder

In Microsoft Excel, you can create a sample Microsoft Visual Basic for Applications Sub procedure (macro) that loops through specified files in a folder (directory) and displays each file name in a dialog box.

This article assumes that you are familiar with the programming language being demonstrated and the tools used to create and debug procedures. Microsoft support professionals can help explain the functionality of a particular procedure, but they will not modify these examples to provide added functionality or construct procedures to meet your specific needs.

1. Start Excel, and then press ALT+F11 to start the Visual Basic Editor.
2. On the Insert menu, click Module.
3. In the module sheet, type or paste the following code:

   Sub DirLoop()
      Dim MyFile As String, Sep As String
      ' Sets up the variable "MyFile" to be each file in the directory
      ' This example looks for all the files that have an .xls extension.
      ' This can be changed to whatever extension is needed. Also, this
      ' macro searches the current directory. This can be changed to any
      ' directory.
      ' Test for Windows or Macintosh platform. Make the directory request.
      Sep = Application.PathSeparator
      If Sep = "\" Then
         ' Windows platform search syntax.
         MyFile = Dir(CurDir() & Sep & "*.xls")
      Else
         ' Macintosh platform search syntax.
         MyFile = Dir("", MacID("XLS5"))
      End If
      ' Starts the loop, which will continue until there are no more files
      ' found.
      Do While MyFile <> ""
         ' Displays a message box with the name of the file. This can be
         ' changed to any procedure that would be needed to run on every
         ' file in the directory such as opening each file.
         MsgBox CurDir() & Sep & MyFile
         MyFile = Dir()
      Loop
   End Sub
   					

4. Press ALT+F11 to return to Excel.
5. On the Tools menu, point to Macro, and then click Macros.
6. In the Macro name list, click DirLoop, and then click Run. A message box appears with the name of a .xls file; click OK to view the next .xls file.
