Hi knowlton,

This line will store all files in a folder with a "xls" extension in a String array....

    Dim Files() as String = Directory.GetFiles("C:\FolderPath\", "*.xls")

What namespace is Directory found in?

Once I call this:

Dim Files() as String = System.IO.Directory.GetFile(strPath, "*.mdb")

How do I loop through each file in Files( )?

Thanks...new to VB .NET

And to browse for the folder first....

        Dim FoldBrowser As New FolderBrowserDialog
        Dim Files() As String
        If FoldBrowser.ShowDialog = DialogResult.OK Then
            Files = System.IO.Directory.GetFiles(FoldBrowser.SelectedPath, "*.xls")
        End If

Oops, sorry. Didn't realised you had posted.

To loop through each of the files once you've got the array, do something like this....

    For Each sFile As String In Files
         'sFile will return the FullPath to the file
