What is a CRF file

CRF files mostly belong to Cal3DViewer by Cal3D. CRF file extension is mainly associated with binary materials created using Cal3D, a cross-platform 3D character animation library. The CRF material file is stored in Cal3D binary material format and contains data of references to 3D mesh overlays that define the appearance of a model's surface as well as properties like the surface's light properties and ambience. Enhanced Dark Engine, a video game development engine uses the CRF file extension to store data such as 3D models, maps, textures and sounds in game archives bundled into video games like Thief: The Dark Project and Thief 2: The Metal Age. CHARTrunner, a Windows-based software for creating charts and statistical analysis from collected data stores chart definitions in CRF files. Print Artist, a photo-card creation software by Sierra stores craft data in CRF files. CRF file extension is also associated with an outdated format for storing C++ and database cross-reference data.

How to open a CRF file

You need a suitable software like Cal3DViewer to open a CRF 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 CRF file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a CRF file directly in the browser:. Just drag the file onto this browser window and drop it.

CRF file extension format:

The file format determines how the data is stored in the file. 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. If the file extension or signature does not match the file format, errors will occur when opening or editing the file. When there is a problem with a file, the first step to solving it is to determine the file format. Below is our analysis of the CRF files:

An CRF file includes various formats for various programs. The two most popular formats are as follows:

20% of all CRF files start with the magic bytes fknc, which are always the first bytes of this file format. They consist of illegible, cryptic characters. CRF files are between 40 KB and 460 KB in size. The file type was developed only in the last few years. Several words can almost always be found in the files, e.g. fknc. These files are often associated with armor, body, helmet, plate, helm, hero, medium and hair.
15% of all CRF files use ZIP compression, i.e. a CRF file contains several compressed files. CRF files contain from 9 to 240 compressed files. You can see the included files and images by renaming the file extension to .zip and then double-clicking it. CRF files can be up to 240 MB in size, but are often around 7 KB - 96 MB. Examples of file names are snd.crf. These files are often associated with date.

All other CRF files (65%) have no uniform format, such as Cal3D material File, XML, DOC, vmpeg, XENC, TRANSPORTABLE, ECO and CASY. Tagged as route, pack, light, purity, report, head or mage. You can get all the details of your CRF file by dragging it onto this page or by clicking the button "Choose your .crf file to analyze" above.

How to solve problems with CRF files

Associate the CRF file extension with the correct application.
Update your software that should actually open 3d model materials. Because only the current version supports the latest CRF file format. Search, therefore, e.g. on the Cal3D manufacturer website after an available Cal3DViewer update.
To make sure that your CRF file is not corrupted or virus-infected, get the file again and scan it with Google's virustotal.com.
