Hi,
Thanks for the response. My (incorrect, I suppose) understanding was that
Accurate=pins5 would just look at an unknown file and determine if it was
an existing file that had been renamed. In that case, I'm fine with taking
the extra time to calculate the MD5 to verify the correspondence of the
files. I wanted this option so that I wouldn't take up space on the tape
with files that had just been renamed. Is there a way to do the same thing
without recalculating the MD5 for files that obviously haven't changed?
Thank you,
B. Smith
