As a graphic designer, I often provide the design files for the projects I am contracted for to the client or to a printer for final output. Many times I get a call or an email from a frantic client worried that they can’t open one of the provided files or they don’t know what the file type is for.
Typically the files types the average person will not be able to open are the files with the extensions AI, EPS, and PSD. Each of these three file types require a special software program used by designers, printers, signage manufacturers, and promotional product manufacturers.
Here is a quick list of the different file extensions you may come across when working with a graphic designer, what each of them stand for, and how the file format is used.
