What Are Bin Files?
Computers use binary code for many purposes. This code is composed entirely of the two digits--1 and 0. When files are written in binary they are often saved as Bin files, with the file .bin file extension. Many different programs use .bin files, from CD-burning software to operating system tools.

Bin File Basics
-
Bin files are not specific to any particular program; instead, they can be used by any software capable of rendering binary. Some programs use Bin files to store configuration data that aren't present in typical registry keys. Bin files often go unnoticed to users because they are system files, hidden by default on most operating systems. Bin files can be opened with script-editing software and even Windows Notepad, but it's not usually practical because binary is not an efficient language for manually writing or editing code.
Bin Files Used By Image-Writing Software
-
CD and DVD writing software often use Bin files to store information. The CD-authoring software Magic ISO, for example, uses Bin files to store copies of CDs and DVDs before they are transferred to disc. One reason CD-writing programs may prefer Bin files is that creating them is less of a strain on a computer's temporary resources than converting to a more complex file type. Bin files are also used in some programs to ensure raw data are copied bit for bit and that no information is lost during transcription.

Bin Files Used for Compatibility
-
Large applications, such as operating systems and virtual work environments, use Bin files to ensure compatibility. Creating new custom file types for small amounts of data can add unnecessary software requirements to programs. Since Bin files can be read by many programs, they are used to make programs compatible with each other, reducing the need for additional software. This practice also saves installation time and space on a computer's memory.
The Types of Data Found in Bin Files
-
Bin files can hold virtually any type of information. Even sound and video can be converted to binary and stored with a .bin file extension. Games sometimes make use of Bin files to store sound effects and other satellite information. Text files are often converted into the Bin format for rendering, and developers often use Bin files to test software.
