Thank you! I appreciate this program very much. I've tried a whole bunch of other programs, and this is the only one that I feel fully comfortable with. Some of them corrupt files (including one from a particular camera manufacturer that corrupts its own maker tags!), and others just don't do what's needed. Now I just have to learn PERL so I can stop being dependent on the Windows version :-) I used to be a software engineer, but I never learned PERL. I guess now is a good time :-)
