@Mutlli good 
and is there old .ldb file?
Something like 000003.ldb file
Open that file with a text editor or code editor software like Atom: https://atom.io/
Once you’ve opened the file, search for the word “ vault or data ” and copy this part that looks like the one pasted below:
MetaMask Vault Decryptor download here: GitHub - MetaMask/vault-decryptor: A web app for decrypting MetaMask vault data.
