What is H file?

The files that comprise of the .H extension is generally the header files used with the C++ or C programming languages. The .H files are called as the ‘header files’ by the programmers. They may consist of an external variable definitions, function prototypes and constants.

The header files mainly are the part of the source code files that are required to use the functions or constants defined in the header. For instance, if you are defining a text string with your business name is the header file, you can make use of this constant everywhere you want to display or else you can use the business name in the source code. If you want to change the name later, you just have to do it from the header and recompile the program to make it effective.

We hope we helped you solve the problem with the H file. If you do not know where you can download the application from our list, click on the link (which is the name of the program) - you will find more information there on the location where to download the secure setup version of the required application.

What else may cause problems?

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

First - the H 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 H 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 H 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 H file has not been completed and it cannot be opened properly).
