What is a HEX file?
A HEX file is a hexadecimal source file typically used by programmable logic devices, such as microcontrollers in remote controls, office machines, and automobile engine control systems. It contains settings, configuration information, or other data saved in a hexadecimal format. HEX files may be stored in either a binary or text format.
HEX files are supported by several editors, including Heaventools FlexHex, Hex Workshop Hex Editor, and HexEdit. If you have a binary HEX file, it can only be opened with hex-editing programs. If you have a text-based HEX file, it can also be opened and edited with a text editor.

.HEX File Association 2
File encoded with an early version of BinHex (binary-to-hexadecimal) encoding software; used for converting files to a text format that could be sent via e-mail without being corrupted; typically takes up more space than the original file.
The BinHex program is only available for the Mac. Newer versions of the program save BinHex files with a .HQX extension rather than ".hex."
