The second method is suitable for encrypting and protecting a single file or folder (and all the files in it). Let's see how to encrypt files with password using Windows' built-in folder encryption feature. This method works in Windows 11, 10, 8 or 7.

Back Up Now

  1. In the Certificate Export Wizard, you will be guided to create an encryption certificate and decryption password. Windows will automatically choose an appropriate format for your certificate, so press Next to continue.

You can confirm the options you have chosen at the final stage. If you are satisfied, press Finish to save the certificate file.
