What Is the BIN File Extension?

BIN, or binary, files are used for a variety of tasks and can be linked to many different software programs. A generally universal file type, they can be anything from a ROM for a game emulator to a data image for a specific program. Unlike normal files like EXE, DOC, or XLS, multi-use BIN files don't have universally predetermined software that's used to access them. They are widely used on both Macintosh and PC platforms.

Definition

BIN files are computer files containing any type of data encoded using binary forms. BIN files are most often created for use with a specific software application, and linking data is stored in a file header to be read by the parent application. However, a BIN file will look like unintelligible gibberish when viewed in a file editor or word processor, and unless there is some clue in the ASCII header portion of the file, it is difficult to determine the program associated with a particular BIN file.

Use

Principally, a BIN file is used to make exact replicas of a file or with a combination of files. In CD burning, BIN files are commonly used when an exact replica of a disk is needed. Burning an image file otherwise would leave out information such as boot information, volume, and system-specific information. When they are used as image files, BIN files come with a CUE file. This tag-along file has extra information so mounting software knows how to handle the BIN file in question.

Dangers

As BIN files are not easily identifiable in their natural form but also commonly chosen as CD image files by users, there are security risks involved in working with them. Hackers can hide dangerous code within image files or BIN files, and then can activate the code remotely to cause havoc with a computer. The creation of security tools made this less of a concern with the arrival of anti-virus or anti-spyware protection systems. Even with these continually updated tools, common sense is still important. Unexpected BIN files from a stranger are best avoided, no matter how enticing they may seem.

Compatibility

Compatibility with BIN files occurs when data files produced by one application are the same as files produced by another application. Numerous companies now produce applications for Windows and Macintosh that are binary-compatible. Therefore, files created in Windows are often interchangeable with those on a Macintosh.

Conclusion

BIN files have an established place within the computer world, and every computer has at least one residing somewhere in it. Their use is varied and ideal in many situations---especially CD duplication---and proper use and care when working with unknown BIN files will keep you safe from computer threats.
