Do I need to convert the SIMATIC OP file to psr. and then upload?

I was able to read the file and signed up with the .psr extension. ProSave can see him now.
What was the reason that he signed up differently, I don't know.
I have another question.
This source project that I want to download after translation.
I connect with the same cable. Do I need to convert the SIMATIC OP file to psr. and then upload?

Thanks.
