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,
