i think someone who is a forum member from 2015 or earlier and is still active on the forum can help.
Those screenshots don't give any info about where they come from. I am not even convinced that the second is indeed a wallet.
It's you who should try to remember if you've used a web service or a wallet application on your computer, it's you who should remember what was that application / service, maybe how it did look like, maybe the file name/extension of the files you made screenshot from...
Without a bit more info, I don't see real chance for getting any help.
Of course, don't post the whole file, don't post private keys and don't answer to possible private messages claiming they can help if you give them the files.
