You will not see the wallet.dat file anywhere in the folder as monero uses wallet.keys for backing up the wallet. You can find the .keys file in the Documents/monero folder of your computer. While you created a wallet file, you would have saved the 25-word seed somewhere in the paper, restore your wallet with the .keys file and this 25-word seed. While you open the backup folder you would find 3 files namely
1. .address.txt - where your address is stored. Just by opening this file you will see your address and no need to open the wallet each time.
2. .keys - where your private key is stored. This is a read only file and the most important file for the backup. You can recover the wallet only if you have this .keys file and the seed words else forget about your wallet.
3. Name - stores all your wallet data and is secured by wallet password.
Ah ok cool thanks man I found it I backed up all those files now
Thanks again
