Final answer:
EFS (Encrypting File System) is supported on various versions of Windows operating systems, starting from Windows XP Professional up to Windows 10, but is not natively supported on Linux. Linux users can access EFS-encrypted files through third-party software.
Step-by-step explanation:
The Encrypting File System (EFS) is a feature available in Windows operating systems that provides filesystem-level encryption. EFS is supported on various versions of Windows, including Windows XP Professional, Windows Vista Business, Enterprise, and Ultimate, Windows 7 Professional, Enterprise, and Ultimate, Windows 8 Pro and Enterprise, and Windows 10 Pro, Enterprise, and Education. On the other hand, EFS is not natively supported on Linux platforms. However, Linux users can access EFS-encrypted files through interoperable products or by using third-party software designed to enable compatibility.
