I decided to share this tips considering it’s very easy and any one can just do it . All you need is Fexplorer which a single google search will take you to the latest version of it .
firstly you need to Insert your password protected memory card into your phone remembering not to access it through phone. then Run FExplorer and Open the path C:system.
from there You will find a file called mmcstore ==> just rename the file to mmcstore.txt
==> Copy that file(mmcstore.txt) to your pc and open with notepad (you can easily drag and drop it from the fexplorer window to an open notepad window
=>>from there You will find your password with just a simple cntrl+f search .
