File extension .H
The H file extension is a C/C++/Objective-C Header File. It generally stores declarations used for the implementation of a C programming language program. It contains variables, constants, and functions declarations. The content in such files used by a C/C++/Objective-C compiler to create an executable program. Each header file uses an associated .c, .cpp or .m file during compilation.
A header file is required for all projects written in any of the supported languages. It allows the programmer to use the same code multiple times without needing to rewrite it, simplifying and speeding up the coding process. Usually, the header will be included at the top of the code and be referenced when calling functions within that script.

After installing the required software, the operating system will usually automatically associate an unknown file type (in this case .H) with the new application. If this does not happen, we can help the system a bit by selecting the software for it, which it should always use to open files with the .H extension.
When choosing the software we can select the system to use this software every time.
Using it for the first time it is good to check whether the .H file opened in the application can be read by us and opens in a way that allows us to use it. If everything is in order, select this option the next time you open a file with the .H extension. However, if the file has not opened correctly, we have to look for a different software, with which we can open files with the .H extension. Select a different software from our list and install it on your computer. After the software is installed, repeat inspection openings of a .H file. Sometimes you have to repeat the operation several times.
If none of the programs listed by us to work with the .H file has not meet your expectations, you can try searching other websites. But remember to avoid downloading programs "that can open any file". These applications not only have very limited functionality, but may also expose you to expense tens of dollars when purchasing a license.
In the vast majority of cases you will find the program dedicated to support the .H file, or any other file format. In addition, there is a chance that it will be a free program, and its functionality (concerning the .H file) will be extended to the maximum.
It is also good to check
- if the .H file has no errors
- or if it has been copied (or downloaded by the browser) thoroughly
