Yes, as I said earlier... it's a password protected, unencrypted wallet file.

So, while the file itself is in "cleartext" and you can read the addresses, transaction history and all the labels... the sensitive information within the file (like private keys, xprv's and/or seed) is encrypted (with AES256 if I'm not mistaken)... using your wallet password.

You should be able to open this wallet in Electrum and see all your history etc. It won't prompt for a password until you try and access the sensitive data (like try to display the seed or sign a transaction etc). Without your wallet password, this wallet file is not much use to you. You can try using btcrecover, but without a good idea of what your password was (or knowing that it was only 8-10 characters long, no special symbols etc) then your chances of being able to bruteforce the password is quite low.


For the record, an Electrum wallet can be in one of three levels of "encryption" as follows... (OP has #2)

1. Non-password protected (Entire file in cleartext, private keys/seeds etc also in clear text):

(NOTE: "xprv" starts with "xprv" and cleartext seed)


2. Password protected, unencrypted (File in cleartext, sensitive data encrypted with wallet password):

(NOTE: xprv does NOT start "xprv", encrypted seed, however xpub (non-sensitive) is still plaintext etc)


3. Password protected, encrypted (file is toally encrypted):

(NOTE: The very last character in the file is most likely a "=")
