What is a QC file

QC files mostly belong to Quake-C by id. QC files are scripts written using QuakeC, a variation of the C programming language which is optimized for developing video games and artificial intelligence applications. Source Engine, a 3D game development toolkit uses QC scripts to compile SMD (Studiomdl Model data) from ASCII text-based 3D models to binary MDL models that can be loaded into various video games such as Half Life and Counter-Strike: Source. The contents of such QC scripts are commands for defining the name of the compiled model, references to locations where materials are stored, and the SMD model's name used to provide the collision, geometry, animation, gestures, and mesh data to be used in compiling the model. These commands are written using C-like syntax. QC file extension is also associated with Progress, a business application development platform. The QC file used by Progress contains query/results configuration such as permissions, printers etc.

How do you open QC files?

You need a suitable software like Quake-C to open a QC 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 QC file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a QC file directly in the browser:. Just drag the file onto this browser window and drop it.

  1. Quake-C by id
    See the previous paragraphs to learn more about the main application. QC files are often referred to as Quake-C games because this type of file is primarily created or used by this software.
  2. Progress (results configuration) by Progress Software Corporation
    Progress is a suite of applications for building and deploying business applications. The QC files used by the Results utility in Progress are generated query/results configuration files containing the list of printers, joins, permissions etc. This file format is classified as Settings.

  3. Steam (3D model compiler script) by Valve
    Steam is a video game management software for Valve games installation, automatic updates, and import/export. The QC file in Steam-compatible games such as Half-Life is a QuakeC script created in Source Engine for configuring and compiling SMD text models to binary 3D models used by games. This file format is classified as 3D Image. Related links: QC, QuakeC, Source (game engine), half-Life (series)

QC file format:

To find out what program is needed to open QC files, you need to determine the file format. Each file format has a unique extension and almost always a unique signature. For example, Microsoft Word documents have the extension .docx and the signature (usually the first 3 characters in this file) PK. Nonetheless, different programs can utilize the same file extension to represent distinct file formats. Double-clicking on the file often results in an error when opening. So a detailed analysis of a file is vital in order to determine the format and the associated program. In the following you will find our evaluation of the QC files:

The QC file extension is not widely used. Such a file covers different formats for different programs. However, the following two file formats are common:

All the rest of the QC files (29%) have different formats. These files are often connected to hggccx, clean, knife, ckdl or male. Just click the "Choose your .qc file to view" button on this page to find out what your QC file is.
