No...you can use OLE Drag/Drop with the vbCFFiles flag to allow a drag from your VB app to ANY drop target that accepts files:
(*note that for this to work, the files being dragged must actually exist!)
Private Sub Picture1_MouseDown(Button As Integer, Shift As Integer, X As Single, Y As Single)
    If Button = vbLeftButton Then
    End If
End Sub
Private Sub Picture1_OLESetData(Data As DataObject, DataFormat As Integer)
    ' The files being copied must actually exist!...
    Data.Files.Add "c:\someFile1.txt"
    Data.Files.Add "c:\someFile2.txt"
    Data.Files.Add "c:\someFile3.txt"
    ' A file that does not exist will generate an error
    ' and cancel your copy operation...
    Data.Files.Add "c:\someFileThatDoesNotExist.txt" 
End Sub
Private Sub Picture1_OLEStartDrag(Data As DataObject, AllowedEffects As Long)
    Data.SetData , vbCFFiles
    AllowedEffects = vbDropEffectCopy
End Sub
