Core does never overwrite a wallet.dat if it already exists in the directory.
Chances are high that this is your old wallet (if it was in the correct directory).
Core does only create a new wallet.dat if there is no in the data directory (standard directory?)
Even if you have deleted the file, under some circumstances you would be able to recover it using some recovery tool and a linux distro.
But, the phrase from your OP is not related to core in any way (maybe your wallet password?).
I have a software program called Recova, its a windows program. I managed to see that there were some files deleted in the recycle bin relating to bitcoin dating back to 2013, and they were called:
blk00013.dat
000346.ldb
rev00029.dat
any reason why it might show these in the recycle bin recovery program?
Also, why should I use Linux distribution to recover files instead of the Recuva program? Is it better? Will it find a lot more files?
Thanks for any help,

Those have have isn't related with Bitcoin wallet or private key at all. I only can think the reason Recuva detect those files because the part of the luckily survived.
FYI, blk_____.dat is blockchain files, ______.ldb is index for all blockchain files and rev_____.dat is UTXO db/chainstate files.
I think he suggest using specialized linux distro which have recovery tools since usually it could find more files and perform better recovery attempt.
@bob123 it would be great if you tell the name of the linux distro or recovery tools.
