Conclusion, I need to open the wallet.dat file with the good Bitcoin Core client... And I can't find it

Did you try extracting the addresses/wallets in it? I saw you can open it with a simple text editor or using a tool that do that automatically, there are existing (but be careful choosing/using a tool, it can be harming)!
Do Bitcoin Core don't gave you the list of your wallets ?

You can just check the balances manually!
I try to extract the addresses/wallets and the balance through the Bitcoin Core client. but for now it doesn't accept the wallet.dat file

you can't open the file with a simple text editor, it's shows unreadable encrypted information. A tool for that? I don't know yet which tool but good idea!

I don't know how but i think the may be corrupted according Bitcoin Core, so the first step is to salvage it.
Thank you for your help
