Well, since we don't support Win9x, we don't need to
worry about that :-) DOS is dead, long live NT :-)
ReadDirectoryChangesW() would be the function, but
I'm pretty sure you knww that.
However, this is a 'best-effort' function;
some notifications can be dropped if the
internal system buffer overflows.
We could, of course, write a file-system filter
driver to accomplish 100% reliability, but that
might be a bit over the top :-)
However, given that moves show up as a add and a
remove, I'm not sure how to detect them... actually,
I suppose we could look at 'add' and 'remove' events
occurring together and then check the newly added file
to see if it contains the contents of the old file.
But that might be too performance intensive.
Thanks,
Joseph
