thanks for both suggestions. i did recover a relatively recent backup on one
machine, but i would still like the version that disappeared. i am not usi9ng
windows offline files. the network drive is connected to my wireless router
and appears as a network device.

How do i change the file extension. obviously not with rename--it just
inserts the .one before the .tmp.
