Opening H files

Did your computer fail to open a H file? We explain what H files are and recommend software that we know can open or convert your H files.

What is a H file?

Files that contain the .h file extension are normally header files used with the C or C++ programming languages. .h files are commonly known by programmers as "header files". They may contain constants, function prototypes and external variable definitions.

The header files are included by source code files that need to use the constants or functions defined in the header file. For example, if you define a text string with your company name in a header file, this constant can be used everywhere you need to display or otherwise use the company name in your source code. Should you later decide to change the name, you only have to do it in the header file and recompile to make the change take effect everywhere.

Try a universal file viewer

In addition to the products listed above, I would suggest that you try a universal file viewer like Free File Viewer. It can open over 200 different types of files - and very likely yours too! Download Free File Viewer.
