And, what they say is that ADS *may* not be supported in future *file* systems, not future *operating* systems. They do say that NTFS will continue to be supported in future versions of NT, as well. So I think saying it "works in NTFS" is pretty accurate, Big Picture-wise, don't you? -- ..NET: It's About Trust! http://vfred.mvps.org

The fact that there is verbage out there that says ADS may not be supported in future file systems should have been worth a mention, link, or other such notice. That's all I'm sayin' LFS

But the "Applies To" list gives away when it was written, as the very low number tends to corroborate >> They do say that NTFS will continue to be supported in >> future versions of NT, as well. >> >> So I think saying it "works in NTFS" is pretty accurate, Big Picture-wise, don't >> you? > > The fact that there is verbage out there that says ADS may not be supported in > future file systems should have been worth a mention, link, or other such notice. > That's all I'm sayin' Yeah, okay, I hear what you're saying. OTOH, no one has ever implied it works anywhere else, including CDFS which is also a common FS these days. And, I'm pretty sure most articles, including mine, say that the ADS "goes away" if you copy/move the file onto a non-NTFS volume. -- ..NET: It's About Trust! http://vfred.mvps.org |
