Using Settings in Windows XP Professional to Keep Files Protected
Clearly, Microsoft is betting that EFS will provide the level of functionality necessary for selling more into the UNIX-centric environments, most notably Department of Defense and key defense-related organizations in foreign countries. The primary concern of having a person simply reinstall a new operating system on a classified workstation and then having access to all classified materials is common in defense-related industries. Through several tests of the EFS approach to tagging specific files, it does show promise in NTFS-centric environments. Yet in the more simplistic file systems of Windows 3.X and even Win 95/98, the lack of robustness that NTFS provides is a cause for concern.
After having confirmed that only my administrator login worked to recover the data in Windws 2000 was I convinced that EFS would work across multiple operating systems.
