How to Encrypt a File on Windows 10 Using Encrypting File System

Microsoft's Windows operating system has a built-in file encryption feature - Encrypting File System (EFS) that lets you encrypt any kind of files, folders, and subfolders.

If you use the Windows encryption tool to encrypt a file or folder, the key is to be logged into the correct user account. This means that different users who are logged into the same user account can view the encrypted file. But encrypted files between different users on the same computer are not viewable and need to be decrypted.

Tips for using Windows Encrypting File System:

  • File encryption is not available in Windows 10 Home. EFS is only available for Windows 10 Pro, Windows 8 Pro, or Windows 8 Enterprise.
  • Files encrypted in this way can still be deleted. So make backups of important files.
  • If you lose the encrypted password, you lose the encrypted file forever. Therefore, it is highly recommended that you back up an unencrypted file or back up your encrypted password.

Step 1. Press Win +E keys to open Windows File Explorer and find the file that needs to be encrypted.  

Step 2. Right-click on the file or folder and select "Properties" in the drop-down menu.

Step 3. Click the General tab, and then click "Advanced".
