Update to "nothing"

Good afternoon,Now this might be a bit stupid - but I've just managed to build an update that completely deletes my application. I simply forgot to put any files in the new "Your program's folder". Everything worked; I thought the update file looked a bit "thin"...Run it and bingo! No app... 😢 OK; so stupid - and once I'd done it about six times I spotted it... 😳 Now; it'd be nice if one of those warnings in bottom left hand corner said "no files in update directory" or something?!Ta, Dr. Michael Dye.
