Digitized files are typically not something you would have. An exception would be if you had one made before, and the company that made it sent you the file. Digitized files are not something that would be included when having a graphic design company make a logo or design for you. They are completely different than vector art files. Digitized files are only for use with commercial embroidery machines.
If you don’t have the proper software (which you generally won’t), you couldn’t even open the file to look at it. In most cases, if you do have a digitized file, you’d also have a “run sheet” to go with it. This is typically a PDF file. It shows the embroidery machine operator the thread colours and sequences of the embroidered design.
