Well, Klaus, first I have to confess that what I *actually* do is just 
run the exiv2 utility from an ugly dosbox (actually, a clean, sparse, 
elegant Emacs shell buffer :-), then run my Rev script, then run the 
utility again .....  (I do this once a month - wasn't worth the coding 
time to build it into a script)

But it can be done from Rev and shell ... I'm not an expert in this, so 
there may be easier ways than this ....

I think a shell is run in the current defaultFolder of Rev - is that set 
to your home folder ?

Here's a script I have used; note I ran into trouble with quoting of 
file names containing spaces - I eventually figured out that I needed to 
quote the command name, and I cheated and moved the files into a folder 
with no spaces in its name, so the "answer" I give when I run this is 
something like "D:\Downloads\aaa"   
I can't find a form that works when my photo folder is say "D:\Our 
Documents\exiv2-0.6.1-win\aaa"
