I wanted to build an awesome place for people to discuss module specific issues, but I don't have any more time for this, and there are much better places to discuss Perl-related issues. I'd recommend asking your question on Stack Overflow or on Perl Monks.
If you are looking for a Perl tutorial or Perl-related news, I hope these links will serve you well.

Creation of par-xxxx directory
Hi Phil,

On Windows, after exiftool.exe is started for the very first time, "par-User" directory is created inside Temp directory. This "par-User" directory contains "cache-exiftool-n.nn" directory, which, again, contains Exiftool related files.
What happens when newer version (than allready present on PC) is running for the first time:
A: complete (old) "cache-exiftool-n.nn" is deleted and new content is generated,
B: "cache-exiftool-n.nn" directory is renamed and only relevant content is replaced.

Thanks for answering,
Bogdan

Re: Creation of par-xxxx directory
Hi Bogdan,

It is the third option:

C: new "cache-exiftool-n.nn" directory is created and the old version is left untouched.

So you can run two copies simultaneously. When you run the old version, it uses the old cache files, etc.

Re: Creation of par-xxxx directory
Hi, For whatever reason (being over-pedantic), I always delete existing "par-..." directory, before I start using new exiftool version -that's why I didn't noticed "C" answer :-)

But now I wonder... does exiftool automatically uses latest "cache-exiftool-n.nn" version (if there are more than one)? How do I influence exiftool to use particular version?

Somehow I have a feeling, you've expected above questions :-)

Thanks for fast response,
Bogdan

Re: Creation of par-xxxx directory
Hi Bogdan,

The name of the cache directory is built into each exiftool.exe, so each version uses the correct cache directory depending on its exiftool version number. You can't make one version of the .exe use the cache from another version without renaming the cache directory.
