I have been able to gain access to a file and was able to open it. It has all of my sending and receiving addresses, seed, type of wallet, xprv and xpub.
You are able to recover your funds with either your seed or your xpriv key.
Simply follow TryNinja's steps to import the seed into a new electrum wallet.
Keep in mind that it is NOT advised to store such sensitive information (seed, xpriv) on your PC.
If you have them unencrypted it might be more convinient (and not much less secure) to simply use electrum without a password.
You should either store such information only 1) properly encrypted or 2) offline (e.g. written on paper, offline pc, ...).
