We have a 12 year old laptop. The laptop has widows 10. Turned it on today to find the screen has changed and all files show as empty. All documents gone and excel files empty.My husband is particularly upset as he does our accounts on it on excel and they have all disappeared. Then he tried to check the accounts on his backup memory stick and seems to have wiped the accounts on that too. I’d be really grateful for any help. I’ve been trying stuff for an hour but no success. Will be out this evening so back to thread tomorrow. And I will be getting a newer laptop soon!,
