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.
does your seed look something like this:
"seed": "stem produce gather bachelor wealth deal electric olympic iron pencil measure daughter"
or something like this:
"seed": "raUdcXYAsPA/YySQi7i8zS/z5TqXNpOWBknGvuzVs1N9iCfW7QIn6am29p+MHFEO4CxWtSggSmmVG/OEl+YT6x+2tY1itGyB9oCoGF8y/1dJ9FBeh+/Fz68MrcwWQ3MU"
If it looks like the first one (ie. unencrypted -> random words), then you can simply restore you wallet using the method listed by TryNinja up thread... and typing in the seed words when prompted... you don't need to worry about having your original password, you can just set a new one.
However, if it looks like the second one (ie. encrypted -> mix of random characters), then what you have is a password protected,
unencrypted wallet file. So, even though the file itself is not encrypted, because you have a password, the sensitive data (like your seed and private keys) is stored encrypted.
In this case, if you don't have a record of your seed words written down somewhere, your only option is to attempt to crack the password using something like btcrecover... which won't work unless you have a fairly good idea what your password was... or it was a very simple password (ie. 8 characters or less)
