It's easy with single file:

exiftool -tagsfromfile apple.jpg -exif:all apple.jpg.mie

Now, what I'm trying to do (for last two hours, grrr), is something like this:

exiftool -tagsfromfile apple.jpg boat.jpg tree.cr2 -exif:all %f.mie
-to get:
apple.jpg.mie
boat.jpg.mie
tree.cr2.mie

Don't need to tell you, that above exiftool line doesn't do the job (and I've tried many other combinations). And it seems so trivial... I'm on Windows (if that matter).
An the solution is?

Greetings,

I think your problems may have been due to a bug I discovered while trying out various commands like this. The following two commands should also achieve the same effect as the above command, but due to this bug they won't create a MIE file as expected:

This will be fixed in the next release, and exiftool 7.10 will work with all of these commands.

I apologize for any inconvenience this caused.
