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.
Below you will find an index of software programs that can be used to open H files divided into 3 categories according to system platform supported. H files can be encountered on all system platforms, including mobile, yet there is no guarantee each will properly support such files.
Being unable to open files with H extension can be have various origins. Fortunately, most common problems with H files can be solved without in-depth IT knowledge, and most importantly, in a matter of minutes. The list below will guide you through the process of addressing the encountered problem.
The most common reason for such problems is the lack of proper applications that supports H files installed on the system. This one is an easy one. Select Microsoft Visual Studio or one of the recommended programs (for example, Borland C++, Eclipse IDE, Dev-C++) and download it from appropriate source and install on your system. Above you will find a complete listing of programs that support H files, classified according to system platforms for which they are available. If you want to download Microsoft Visual Studio installer in the most secured manner, we suggest you visit Microsoft Corporation website and download from their official repositories.
You still cannot access H files although Microsoft Visual Studio is installed on your system? Make sure that the software is up to date. It may also happen that software creators by updating their applications add compatibility with other, newer file formats. If you have an older version of Microsoft Visual Studio installed, it may not support H format. All of the file formats that were handled just fine by the previous versions of given program should be also possible to open using Microsoft Visual Studio.
If you have the latest version of Microsoft Visual Studio installed and the problem persists, select it as the default program to be used to manage H on your device. The next step should pose no problems. The procedure is straightforward and largely system-independent
The procedure to change the default program in Windows
The procedure to change the default program in Mac OS
You closely followed the steps listed in points 1-3, but the problem is still present? You should check whether the file is a proper H file. Being unable to access the file can be related to various issues.
If the file is infected, the malware that resides in the H file hinders attempts to open it. Scan the H file as well as your computer for malware or viruses. If the H file is indeed infected follow the instructions below.
If you obtained the problematic H file from a third party, ask them to supply you with another copy. The file might have been copied erroneously and the data lost integrity, which precludes from accessing the file. When downloading the file with H extension from the internet an error may occurred resulting in incomplete file. Try downloading the file again.
Sometimes in order to access files user need to have administrative privileges. Log out of your current account and log in to an account with sufficient access privileges. Then open the C/C++/Objective-C Header Format file.
If the systems has insufficient resources to open H files, try closing all currently running applications and try again.
Up-to-date system and drivers not only makes your computer more secure, but also may solve problems with C/C++/Objective-C Header Format file. It may be the case that the H files work properly with updated software that addresses some system bugs.
