In C there only is this folder
https://en.bitcoin.it/wiki/Data_directorybitcoin.conf must be in the
blockchain directory where you has the
blocks directory, too (local blockchain).
blockchain directory have wallet.dat, adresses.dat, banlist.dat, etcs ... and bitcoin.conf that you must create (not provide by the setup of Bitcoin Core).
I create the file in the principal folder i will check if this files are in a subfolder. Now i have to use another computer for 2 days or maybe for months

so i have to redownload the blockchain and everything on the computer that i actually use. When i finish i will try again
