Does anyone know how to delete a file safe when you forget the password on a honor x8?

I had a file safe where I put pictures of important stuff like my credit card, birth certificate, and log in passwords incase I forgot anything now I forgot the password to the safe and the security questions so I'd rather just delete it since I don't want those stuff clogging my phone up since I can't even use it

I tried going to files app then in the corner go to settings to see if I could delete it but nothing pls help
