File

A file (also referenced as a computer file) is a collection of data stored on a computer system under a unique filename. There are various categories of files; the most widely used file types include document files, image files, audio files, video files, log files, software library files, and application files. 

Each file category contains various file formats. For example, image files contain an array of formats such as JPEGs, GIFs, BMPs, or PNGs. Computer users can determine a file's format by viewing either its file icon or its file extension (which is often a part of its file naming scheme). 

Files can be opened, saved, deleted, and organized in file folders. In a business setting, employees typically transfer files throughout their organization over a company network as a means of information sharing.
