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.

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
