In order to lock a folder on a Windows 10 Pro laptop, you will have to go to the ‘Properties’ of the folder.

  1. Open your laptop and find the folder you want to lock.
  2. Right-click on the folder and select ‘Properties’.
  3. Click on ‘Advanced’ in the ‘General’ tab.
  4. At the bottom of the ‘Advanced Attributes’ menu that pops up, check the ‘Encrypt contents to secure data’ box.
  5. Click ‘OK’.
  6. You will be taken back to the main ‘Properties’ window, click ‘Apply’.
  7. Next, ‘Confirm Attribute Changes’ menu will pop up, choose between ‘Apply changes to this folder only’ or ‘Apply changes to this folder, subfolders and files’.
  8. Click ‘OK’.
  9. Click ‘Backup now’ to backup your file encryption key.
  10. Connect a USB pen drive and follow the on-screen instructions to export the encryption key to the drive.

The last two steps are crucial so that you don’t lose access to the protected folder in the future. In case you choose to skip these steps and forget the password, you will not be able to access the folder anymore.
