If you do need to refile, you actually don't! To bring an IFR flight plan forward, you have to cancel and re-file, but with a VFR plan, you can just send a CHG with the new ETD.
Interestingly while on route from Lisbon back to Malaga on a VFR flight plan the enroute controller said that I should have had an airways intersection waypoint close to the Portuguese/Spanish border in my flight plan route, he asked me to pick one then fly to it as my ‘border crossing’ point which I thought was strange.
