I would likw a very simple piece of code that (given a starting folder) will loop and return into an array every directory/filename combination (format ready for Open statement) in a directory and all its subdirectories. No special order is required. Thanks.

Try this
 
 

Option Explicit
 

Dim mlngIndex As Long

Dim gstrFiles() As String
 

Private Sub Command1_Click()

    Call ListFiles("c:\temp")

End Sub
 

Private Sub ListFiles(strFolder As String)

    Dim oFs As Object

    Dim oFile As File

    Dim oFolder As Folder

    Dim oSubFolder As Folder

   

    Set oFs = CreateObject("Scripting.FileSystemObject")

    Set oFolder = oFs.GetFolder(strFolder)

    If Err.Number > 0 Then Exit Sub

   

    For Each oFile In oFolder.Files

        mlngIndex = mlngIndex + 1

        ReDim Preserve gstrFiles(mlngIndex)

        gstrFiles(mlngIndex - 1) = oFolder.Path & "\" & oFile.Name

    Next

    

    For Each oSubFolder In oFolder.SubFolders

        Call ListFiles(oSubFolder.Path)

    Next

  

    'Clean up

    Set oFs = Nothing

    Set oFolder = Nothing
 

End Sub

Open in new window

ReDim Preserve will slow it down significantly if you have a large number of files...

...you could use a Collection instead like in my old example here:

Idle_Mind is correct about the ReDim slowing things down. But your question did say "loop and return into an array every directory/filename combination". Probably should have given you what you needed not what you asked for.
