When accessing Laserfiche through WebDav (using Windows Explorer), when documents doesn't have any extension in the Laserfiche document name, then no extension is present when looking at these documents through Windows Explorer. SO the associated application can't be done and can't be opened.
Can Laserfiche change that behavior (on the server side) where if there is not file extension in the document name (compared this to the internal system extention field for this same document), then add an extention to the document name so all WebDav side documents have a file extention.
