File Extension Library

File Extension Library

Ever wondered; “What is that file?” or “I wonder what that file does?” or even “Gee, I hope that’s not a virus?” Need not despair, the psyborg® file extension library is here. An A-Z listing of design related file types, providing you with file type acronym, meaning and explanation of file usage.

I hope this will be a helpful tool, especially now that everyone is beginning to interact with digital technology.

Below is a list of design related file types that a typical multimedia designer would be familiar with. It is not a complete list as there are a huge number of software applications out there, however the list below is indicative of the standard file types used in the Graphic Design & Multimedia industries.
