IMatch uses the awesome ExifTool library to read and write metadata. This ensures optimal metadata quality and compatibility with a wide range of applications, digital asset management systems and web services.
ExifTool uses a Perl runtime environment. When an ExifTool version is first run on a computer, it creates a sub-folder in the system TEMP folder and extracts a copy of the Perl runtime files into that folder. This is basically it’s installation process, if you will.
The name of the folder is par-User where User is the user account name under which you log in. In my case, the folder is named par-Mario:
Every time IMatch ships an updated version of ExifTool, a new sub-folder is created, but the old folders are not automatically deleted. If you don’t clean the TEMP folder on your system automatically or at regular intervals, these old folders can take up quite a lot of disk space – about 15 MB for each folder. If you work with multiple users on the PC, a folder is created for each user.
Deleting the par-User Folder
When IMatch is running, close it. You cannot delete the folder while IMatch/ExifTool are still running.
To open the TEMP folder on your system, type %TEMP% into the Windows Explorer address bar and press <Enter>:
Then locate the par-User folder and delete it. ExifTool automatically generates a new folder for the current version when you start IMatch the next time.
This information is also available in the IMatch help, in the ExifTool, Technical Reference topic.
