*_wallet file.
Try searching for *wallet*. The first time Electrum creates a wallet it'll name it default_wallet, and all subsequent wallets will be named wallet_1, wallet_2, so on and so forth. Also try to recall if you had given it another name, such as weedfunds, or some such silliness.
I take it this was before bip32 seed phrase implantation?
I can found a folder named Electrum (Was run by windows), i would say I was using the portable version tho.
Couldn't get any file named default_wallet or something like that, not sure If I gave this wallet I name but I'd say I choose the default name
All I got is blockchain_headers, config, recent_servers files and then a "certs" with DNS names and a bitcoins.sk file
Can I do something with this..?
If Electrum was installed on your system the directory where the wallet files are stored will be "C:\Users\<username>\AppData\Roaming\Electrum\wallets". If you were using the standalone version it should have created the "wallets" directory files in the same directory where the executable file is located.
You wont find any file named "seeds." The Bip32 (and subsequent Bip39) implementation allow us to create a wallet backup "seed phrase." These mnemonic phrases consist of 12 to 24 common dictionary words. The phrase would not have been stored on the computer, but rather you would have been instructed (during setup) to write down the phrase and store it someplace safe. If you have a seed phrase then you can stop searching for the old wallet files. The phrase can be used to restore your wallet and all your funds.
