Yep, I seem to get replies from Microsoft, but I had one reply that seemed useful. I guess someone has cleverly subscribed them to the list. My interest in HFS (and infact Macs) has come about after having to support an office full of them, and wherase over the last 5 years, I've become to love Linux, and find it quite capable of supporting networks of Windows PC's, there doesn't seem the same level of support of Macs. Since Apple has made the step towards POSIX, I think that should change. I can happily take a Windows PC's HardDisk, stick it in my Linux box and fix pretty much anything with tools I can find, wheras for Macs, I can't even read anything after OS 8. Also I work on Netatalk, so I looked into some of the well documented Mac specs, and believe core to implementing a nice fluffy AFP server, you need a CatalogFile. Hence the HFS connection. Simon
