Dear experts,

I have this to load and save the 3 listviews to file.

procedure TMainForm.FormClose(Sender: TObject; var Action: TCloseAction);
begin
  SaveListViewToFile(lstvGlucose, 'Glucose.sav');
  SaveListViewToFile(lstvBolus, 'Bolus.sav');
  SaveListViewToFile(lstvFoodDB, 'FoodDB.sav');
end;
(*---------------------------------------------------*)
procedure TMainForm.FormCreate(Sender: TObject);
begin
  LoadListViewToFile(lstvGlucose, 'Glucose.sav');
  LoadListViewToFile(lstvBolus, 'Bolus.sav');
  LoadListViewToFile(lstvFoodDB, 'FoodDB.sav');
end;

But when I start my application the first time the files doesn't exits yet.
so, I get 3 times a error message. How can I prevent this.
That the programm first look if the fileexist otherwist create it.
