Sure I can make the column wider each time but that’s not a very friendly way each time.
Enlarge with Option key is working in when you call it with Apple script in the editor.
Within a VBA macro it will not work, for example
Sub Select_Folder_On_Mac()
Dim folderPath As String
Dim RootFolder As String
On Error Resume Next
RootFolder = MacScript("return (path to desktop folder) as String")
'Or use RootFolder = "Macintosh HD:Users:YourUserName:Desktop:TestMap:"
folderPath = MacScript("(choose folder with prompt ""Select the folder""" & _
"default location alias """ & RootFolder & """) as string")
On Error GoTo 0
If folderPath <> "" Then
MsgBox folderPath
End If
