Steps to password protect any file or folder on Android
Step 1. First of all, you need to download an application called File & Folder Locker. This application will help you lock files and folders.
Step 2. After installing the application, this application will request 2 permissions. 1) access to your files and storage, 2) read your contacts. Grant 1st permission access and opt out of 2nd. We do not want some application to read your contacts.
Step 3. After granting permissions, the application will prompt you to set a new PIN. Create any 4-digit code that you can easily remember.
Step 4. After creating the PIN code, you must add the email identifier, so if you ever forget your PIN code, the application will send your PIN code to this email address.
Step 5. Now you will see all your files and folders in the application, here you can see which file and folder you can lock. The application displays a green lock icon along with files and folders, which means that you can lock this file or folder.
Step 6. From there, you can lock any file or the entire folder by simply clicking on this file and it will ask you if you want to encrypt this file, click "encryption".
Step 7. After encryption, you will see the unlock button next to this file.
Step 8. Whenever you want to use this file again, you must decrypt it, and it is very simple. Just open the application and browse to the desired file, and it will ask for a PIN code. Enter your PIN and click "decrypt", the file will be decrypted.
That's all, I hope you enjoy this method of locking folders and files.
