What is HEX file?

Files with the HEX extension are source files utilised to save various data stored in hexadecimal system. They may include settings, configurations or other information.

HEX files may be encountered in text or binary form. HEX text files can be opened easily using a standard text editing program, but in order to display content of binary files, a special hexadecimal editor is required . HEX file is a result of conversion of source code into machine code.

Where HEX files are used?

Data contained within HEX files is used by compilers and assemblers in the process of writing code controlling microelements, such as built in systems, the EEPROM or FLASH memories. Microelements are installed in many commonly used devices, both less and more advanced, e.g.: remote controllers or systems controlling a car engine.

Structure of data in HEX files

Hexadecimal data in a HEX file is stored in lines of text, and each of them consists of six elements:

  1. Start tag – a colon;
  2. Number of baits – two digits in hexadecimal system which define length of the data record;
  3. Address – four digits in hexadecimal system which enable to address up to 64K of memory per a single segment;
  4. Type of record – two digits in hexadecimal system, from 00 to 05;
  5. Data – data configuration which stores a bait in hexadecimal text form;
  6. Checksum – two digits in hexadecimal system which constitute checksum of the record without a colon.

What else may cause problems?

There can be more reasons which determine that you are not able to open the HEX file (apart from the lack of the proper application installed).

First - the HEX file may be incorrectly associated with the application installed to support it. In this case, you need to change this association by yourself. To do this, right-click on the HEX file that you want to edit, click "Open with" and then select the program from the list that you have installed. After this operation, the problems with opening the HEX file should be solved.

Second - the file you want to open can simply be damaged. Then, the best solution is to find a new version of given file, or download it again from the same source as before (maybe for some reason in the previous session the download of the HEX file has not been completed and it cannot be opened properly).
