Hi! Beginner here.

Long story short, my brother gave me his old laptop years ago and recently I found a bitcoin folder in the temp directory. I kept all the files within except for the old block chain, which at the time was only a couple gigabytes, but am having troubles opening it in a new wallet in bitcoin core. I synchronized with the chain and made a wallet with the new wallet.dat but it says that it may be corrupted, but when i include files like, .walletlock db.log and blk.index, it says its loading the wallet, but for an insane amount of time. So long that it usually says it failed because the chain desynced after 4 or so hours. There are more files that i kept within the wallet like pywallet.py and such and truly im not even sure this wallet is from bitcoin, so any help will be appreciated, ill keep an eye on this post.

Also i told my brother about this already and he said its fine that I try and recover the wallet, but he also doesnt really know how either.
