What is a PSN file?

PSN files mostly belong to CATIA V5. The PSN file is a CATIA V5 session file that stores product structure information during an active design session. It captures a snapshot of the product’s assembly and hierarchy at a given moment in the CATIA environment.
Usage Details:

File Content: Contains temporary design and structure data used to maintain session context.

Functionality: Allows CATIA V5 to resume work with accurate product data and connections between parts.

Accessibility: Can only be opened and viewed using CATIA V5 or compatible software.

FilExt.com tip: If you work with these sessions, it is best to use CATIA V5 as it reads the file structure correctly and updates it during your design process.

How to open a PSN file

You need a suitable software like CATIA V5 to open a PSN file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your PSN file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a PSN file directly in the browser:. Just drag the file onto this browser window and drop it.
