Windows Encrypting File System (EFS) is a built-in encryption technology in Windows operating systems that helps users protect their sensitive data from unauthorized access by encrypting their files and folders. If you enable EFS on your Windows computer, it will encrypt your sensitive files with a unique key that only you can access with your login credentials.

The Windows EFS feature is available on all the Windows operating systems; Windows 7, Windows 8, Windows 8.1, and Windows 10. Enabling EFS is relatively easy, and users can do it by following a few steps. Here is how you can enable or disable EFS on your Windows computer.

Step 2: Right-click the file or folder you wish to encrypt, and select Properties.

Step 3: Select the General tab, and then click the Advanced button.

Step 4: Click the Encrypt contents to secure data checkbox, and then click the OK button.

Step 5: After completing the above steps, Windows will automatically encrypt the file or folder.
