This example uses the Dir function to check if a certain file exists.

Dir Function Syntax:

   Dir[(pathname[,attributes])]

Visual Basic for Applications Sample Code:

   Sub DoesFileExist()
      Dim MyFile as String
      ' Returns "My Document" if it exists.
      MyFile = Dir("HD:MyDocs:My Document")
      If MyFile <> "" Then MsgBox "File Exists."
   End Sub

NOTE: To avoid getting an error, you must specify pathname the first time you call the Dir function.

Dir returns the first file name that matches pathname. When no more file names match, Dir returns a zero-length string (""). Once a zero-length string is returned, you must specify pathname in subsequent calls or an error occurs.

For more information about the Dir Function, while in the Visual Basic for Applications Editor, click the Office Assistant, type "Dir" (without the quotation marks), click Search, and then click to view "Dir Function."

NOTE: If the Assistant is hidden, click the Office Assistant button on the Standard toolbar. If Microsoft Visual Basic Help is not installed on your computer, please see the following article in the Microsoft Knowledge Base:
