As far as I know EFS appeared in Win2k.

Harry.

 

I believe it's only supported by NTFS5 so the answer is no.

By the way, one question I've seen come up time and again on various practice exams are the differences between NTFS4 and NTFS5 so it's worth knowing the two main differences - NTFS5 introduced EFS and disk quotas IIRC.

 

Professor Falken,

Which version of "Windows NT?"

 

i say yes (although it did not come in my exam).

the reason for this is, as EFS is under NTFS5, there are questions for NTFS5, so maybe it may come up. best thing is to learn the topic to be on the safe side, even then if it doesn't come up, at least there is something else you've learnt...

 

Prof, are you asking does NT4 support the encrypted file system (EFS) that was introduced in Windows 2000? If so the answer as far as I am aware is no.

Windows 2000 and XP are all built upon NT technology, hence the confusion.

NT used to stand for 'New Technology' but Microsoft have erased most traces of that as the technology got old.

 

Was there not a service pack for NT to update it to NTFS5?

 

SP4 gave NT the ability to read NTFS5 volumes but I'm not sure if you could actually convert the NT system volume to NTFS5.
