How to open a file with the extension prt.14?

Question

Data storage

The client threw off the file in the prt.14 extension, I'll never know how to open it. I would be grateful for any advice.
The file name looks like this: ceret11.prt.14

Answer 1

In general, you need to open it in Pro / Engineer, and if the model was created after 2015, then in Creo Parametric
