Hello ,
Probably is the most common topic but i couldn’t find an answer by reviewing post topics .
1. I use to mine bitcoin back in 2010,
2. I have transferred the rewards to bit coin core wallet. Then i spread it to few addresses within 2 wallet.
3. I have encrypted all information in few ways and format my hard disk (windows 7)

    - encryption 1: encryption of all files with encryption software which I have no clue which one I was
( I have few files which I suspect to be key file and container ) maybe using VM

    - encryption 2: files made with paint with the QR of every address in the wallet
                          - same with: word, PowerPoint, photoshop, excl. the files as been corrupted by removing    header of file and change of the extension

     - encryption 3: the bin folder with the files inside (but I’m not sure about it)

* I have protected many windows files and information ( basically all the windows folder) if I need to restore the user somehow
* if I remember right part of the transduction I did while the wallet is closed

Thank you all so much
