ok guys this is getting bloody tense, have found some files by searching wallet. I've realised before going any further I need back all this up
Good decision, but avoid cloud backup if you have another medium (such as different computer or USB flash drive).
It's a hidden folder, you either have to type it in the File Explorer address bar like C:\Users\yourself\AppData
You also can type
%appdata% which open
C:\Users\[your windows username]\AppData
