Microsoft support engineers can help explain the functionality of a particular procedure. However, they will not modify these examples to provide added functionality or construct procedures to meet your specific requirements.

You can use the Dir function to check for an existing file by passing thefile name and path to the function. If the function returns a zero-lengthstring (""), the file does not exist.

The following sample code checks for the existence of the Autoexec.bat filein the C:\ folder. If the Dir function returns a zero-length string, thefile was not found, so a message box displays "No such file!" If the Dirfunction finds C:\Autoexec.bat, a message box displays "File exists!"

Sample Visual Basic procedure

   Sub DoesFileExist()      Dim FileInQuestion As String      FileInQuestion = Dir("C:\Autoexec.bat")      If FileInQuestion = "" Then         MsgBox "No such file!"      Else         MsgBox "File exists!"      End If   End Sub
