What is a .prin file?

[MisterAdvent]

With build 58, I notice a .prin file is created with the project. Windows says it's an "Adobe Media Intellegence Project Index File."

What's that supposed to do???

Thank you for your feedback.

This is used by the new Media Intelligence feature (https://helpx.adobe.com/premiere-pro/using/media-intelligence-and-search-panel.html) for searching your project based on visual information. You can find the new search icon in the top right of the header bar. The index file stores all the processed information about the clips in your project so it is immediately available when you reopen it.

Best regards,
