I reinstalled the system and I want to know how I can retrieve my wallet and BTC

[w986746302]

hi I reinstalled my windows10 system a week ago and just remembered that my Electrum program still has my wallet and BTC
Because this wallet is my temporary wallet, I carelessly did not record the private key, I only put him in the Electrum program, I want to know if I still have a way to restore it, or which recovery program can help me Restore the entire Electrum program and data so I think I can find my wallet too
thank you all

Did you completely wipe and reinstall the system? Windows has an option to reinstall whilst keeping the data in a directory called Windows.old.

If you're lucky enough, you can try using data recovery program like recuva to recover files if they're not overwritten yet. In any case, don't touch the hard drive storing the wallet for the time being and use another computer to use recuva.

But I don’t know which file Electrum saves in the wallet. If I know, I may be able to restore this file through the recovery program.

Your wallet data ends up in the "%AppData%\Electrum\wallets" folder. This is likely to be something like: C:\Users\YOURUSERNAME\AppData\Roaming\Electrum\wallets

In the "wallets" folder you'll find all the individual wallet files listed by the name chosen when the wallet was created. The "default" wallet is usually called "default_wallet"

DO NOT WRITE ANY DATA TO IT. Even installing some small programs/browsers and maybe even temporary files while we are talking will make it difficult to recover data.
If you don't use the computer, stop using it, and ask an expert to help you recover safely.
The best-paid program (depending on my personal use) is Easeus data recovery^[1].

So you hadn't wrote your seed phrase during installation? If it were saved then it would be very easy to recover. Try to find your wallet file as mentioned by above users, perhaps it would still exist on your old windows folder.

If you are failed to find and recover your wallet then likely wallet recovery service would help you. They are well reputed on this forum but they would ask 20% fee from your total funds.

Hope your problem will be solved soon.

Thankfully it was a temporary wallet! You should always backup your wallet file and save your seeds.

All you need to recover is the wallet file ( +password if it was encrypted) not the entire software.
I recommend using recuva to recover your lost files. I used it before but sometimes I just end up with corrupted filles.
