Please, modify the title to "How to Recover a fresh Deleted Cryptocurrency Wallet."The file recovery process also depends on the modification to the hard drive after the formatting process. So the best advice is "do not modify your files"create a new one" after formatting if you want to restore files."
Download recovery software free trial on the computer you deleted the wallet from. WINDOWS DOWNLOAD – MAC DOWNLOAD
Personally, I believe that downloading any new files, "even this program" will reduce the chances of recovery.
If you have located the missing wallet, it is likely worth upgrading to the full version to recover your file, depending on the value tradeoff.
You do not need to download a whole blockchain but bitcoin core (the only wallet uses the wallet.dat format)
1. use prune ( reduce disk-space).
2. use dumpprivkey and export your Pvt key into SPV wallet.
