Open HEX File

In subsequent paragraphs, we would come to understand what “HEX” means as far as computer technology is concerned. We’ll also show you a guide to open HEX File, convert and work with such files and what they are meant for.


What is .HEX File Extension

If you are surprised to see the words ‘File extension’ attached to ‘.HEX’, I would not say I blame you. A .HEX file extension is a Hexadecimal Source File. If you are already counting out to see how many numbers are in a Hex, well that is cool.

How to Open HEX File

A Hexadecimal is a method of representing numbers using the base-16 number system. While counting in this system, numbers immediately after ‘9’ would be represented by an alphabet, where 10 is A, 11 is B and so on. For example, 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, etc.

It gets complicated down the line. Number 24, for instance, would be 18, as in 16+8 where 16 takes the place of 10. The number 100 would be 64 and calculated thus; 16×6 + 4. It gets a bit complicated the higher we go, but I do not think you are here for all that.

As complicated as the calculation may seem, the base-16 system is usually more efficient because one hexadecimal digit represents four binary digits and whereas it takes eight binary digits to represent one byte, only two hexadecimal digits would do the same thing. Cool, I know!
