What Is It? How To Open A GCH File? - FILExt

Opening a GCH File

The GCH file type is primarily associated with GNU Compiler Collection.

GCH	File extension: GCH
	File type:	precompiled header

What is a GCH file?

GCH files mostly belong to GNU Compiler Collection by Free Software Foundation. A GCH file is a precompiled C or C++ header generated from a H (header) file using GNU Compiler Collection (GCC). A precompiled header contains compiled code which is imported into multiple source code files (e.g. CPP) in a project. A CPP file is essentially the binary version of a H file. It contains reusable variable, class, methods, and interface declarations. A precompiled header is only compatible with the compiler version used to create them.

How to open GCH files

You need a suitable software like GNU Compiler Collection to open a GCH file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your GCH file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a GCH file directly in the browser:. Just drag the file onto this browser window and drop it.

Programs that open and convert GCH files:

1. GNU Compiler Collection by Free Software Foundation See the previous paragraphs to learn more about the main application. GCH files are often referred to as GNU Compiler Collection developers because this type of file is primarily created or used by this software.
2. Visual Studio (precompiled header) by MicrosoftVisual Studio is an integrated development environment for building desktop, mobile, and web applications. When configured to compile C and C++ code with GCC, Visual Studio saves a precompiled header in a GCH file. This file format is classified as Developer.

GCH file format:

Every file has a defined file format, i.e. how the data is arranged in the file. The initial characters of a file are called signature, sometimes also referred to as "magic bytes". The signature can be used to infer the file format. However, different programs can use the same file extension, and file extensions can be assigned incorrectly. If there are problems opening a file, you must first determine the file format used. Below is our analysis of the GCH files:

GCH is rarely used as a file extension and mainly uses a defined GCH format. The following file formats are most commonly found in GCH files:

• 70% of all GCH files have the same signature gpc. These are binary files, so they do not contain words or text. GCH files can be up to 98 MB in size, but are often around 1 MB - 21 MB. The file type is relatively new. The following keywords are characteristic: x86-64 and gpch+014. Such files are related to data.
• 15% of all GCH files have the same signature CPCH. They consist of unreadable binary data. GCH files can be up to 51 MB in size, but are often around 200 KB - 11 MB. Several words can almost always be found in the files, e.g. B(<0G+, B)<DI+ and CPCH.

All other GCH files (15%) have no consistent format, often, for example, font. You can get all the details of your GCH file by dragging it onto this page or by clicking the button "Choose your .gch file to analyze" above.

a gch precompiled header is a special file format by Free Software Foundation and should only be edited and saved with the appropriate software.

How to solve problems with GCH files

• Associate the GCH file extension with the correct application.
• Update your software that should actually open precompiled headers. Because only the current version supports the latest GCH file format. Search, therefore, e.g. on the Free Software Foundation manufacturer website after an available GNU Compiler Collection update.
• To make sure that your GCH file is not corrupted or virus-infected, get the file again and scan it with Google's virustotal.com.
• Click here to open your .GCH file online - secure, fast, and no downloads needed.
