Does the OS send out any kind of monitorable event when a file is
modified on disk?
(I'm still working on fast, effective sync between a desktop and laptop,
and the best way would be if each machine could keep a current list of
its own modified files. The best way to do that, I think, would be if
the sync program could listen for modified files instead of searching the
entire directory structure every so often.)
I would instead keep a Md5 hash of each file and not rely on the date at
all. if the two machines clocks are not in sync then it will be kind of
useless.
You could store the Md5 hash of the original file then you could tell on
which machine the file changed. then ask the user which on to keep etc...
(Md5 is part of Openssl etc...)
