So much time I was spending my time on the internet finding a solution to unlock a password-protected 7zip file but did not get the best results. But one day I found a tool, which solved all my problems. I suggest you get eSoftTools 7z password recovery software. This software recovers deleted passwords and show the password to users. This software has 3 techniques that open the password of a locked 7z file: Mask Attack, Brute Force Attack, and Dictionary Attack.
