There is a file called ‘test.txt’ in the folder which content as the figure below.In this example, I’ll encrypt a folder called ‘Data’ and all files in this folder.You have to configure addtional steps on domain controller. For a computer that is joined to a domain, it’ll diferrent from here. They can login with your account and have all access as it was you.īelow, the example shows how to implement EFS on Windows XP Professional which is a stand-alone computer. Note: With this approach, it’ll be useless if others knows your password. The encryption and decryption will be performed on background, no need to perform additional task for user. Other users who hasn’t this key can’t decrypt the files so that they can’t read or copy the files. EFS (Encrypting File System) is a feature on Microsoft Windows XP Professional (Not available in Home Edition) and Windows Server 2003 that encrypt files or folders on disk with user’s key.
