the ext2 IFS (addin) for windows NT/2K with source http://uranus.it.swin.edu.au/~jn/linux/ext2ifs.htm and most importantly a free copy of the IFS header stuff: http://www.acc.umu.se/~bosse/ i don't really know if this is enough to build the filesystem stuff but i believe so. although i'm not even sure if it's worth the effort right now because as Microsoft points out on their web page, one of the reasons this isn't included in MSDN is that it's unsupported and this API could change at anytime. this means that once microsoft finds people writing products it doesn't like that haven't paid them: <chop>. the standards change and microsoft makes everyone else upgrade again. -soco
