How do I upload a standard environment to my library?

Hi

The library contains a blank template or standard template, except for the data that comes in the product.
So how do I register each file in the library?
The files I want to register are fonts and template, symbols.
Each extension displays such as .prt.1 or .tbl.1.
CREO does not recognize when registering through the creation of new documents.
How do I post?
