AC Question

I have an old LG Optimus S LS670 with a screen lock I've long forgotten. This phone has my daughters baby videos on it. This phone is no longer linked to my google account as I've not used it for 3 years maybe longer. I want to know if their is anyway I can unlock this damn phone and retrieve my videos. Ive connected it to my computer but it says its empty do that mean its already been reset?
