It's not the same. There are subtle but important differences, that rarely 
show through everyday use but make the difference in complex scenarios. 
This is because the underlying model for filesystems is different: VFS on 
UNIX, IFS on Windows, and VFS is by far the best of the two. If it wasn't 
for the whole driver compatibility thingy, I wouldn't even have bothered 
with IFS, and would have gone straight for VFS. Just about the only thing 
about IFS that doesn't completely suck is the cache manager - the rest is 
forgettable garbage, and Microsoft's licensing of the IFS SDK hasn't helped 
either
