File Formats definition
A digital file’s information is stored in different kinds of file formats. Either the formats are based in the application program that first made the file (.doc is a Microsoft Word file for instance) or a standard format that is understood by the majority of imaging programs (like JPG). Some file formats will take the information and compress it so it makes files smaller. This in turn helps to save storage space and better facilitates sending e-mails of the digital information. However, during the compression process information is lost. Examples of such formats include AI, EPS, JPG PSD, and TIFF.
