What is a VTX file?

VTX files mostly belong to Source Engine tools. Most VTX files are used in the Source Engine model system. They hold data that defines how vertices connect to form a 3D model.
In this context the file works with other assets, such as *.MDL and *.VVD files, to ensure models render efficiently in real-time gaming.
Source Engine Usage:

Stores vertex order and mesh connectivity information.

Is compiled during model processing to optimize game performance.

Operates in conjunction with related model files.

For further technical details, see the Source Engine documentation.
A smaller group of VTX files serve another role. These files are used as video thumbnail images. They capture a still frame from a video, typically in JFIF format, and can be viewed with standard image software.

Used to preview video content.

Manage still images generated by utilities like Video Thumbnails Maker.

VTX file format details:

A file format defines how the data in the file is structured. The file format can be deduced from the file extension and the signature. File extension, signature and file format must match; otherwise errors will occur when the file is opened. When there is a problem with a file, the first step to solving it is to determine the file format. Our evaluation of the VTX files looks like this:

VTX is a very common file type and is mainly used by one program with a specific format. The following file formats are most commonly found in VTX files:

85% of all VTX files use the same file format, which have the signature 07 00 00 00. The content consists of illegible binary data, which can only be read and interpreted by the associated programs. The files are on average 150 KB in size and range from 8 KB to 820 KB. The file type was created 10 years ago, but is still used today. Such VTX files store data about arms, pyro, portalgun, woman, survivor, soldier, rifle, pist and snip.
7% of all VTX files are based on the popular JFIF file format. JFIF is short for JPEG File Interchange Format. It is a bitmap graphic that uses JPEG compression. These are binary files, so they do not contain words or text. The files are on average 400 KB in size and range from 170 KB to 1 MB. Several words can almost always be found in the files, e.g. JFIF, Video Thumbnails, SUU Design, xExif and Video Thumbnails Maker v13. Such VTX files store data about movie.

The remaining 8% of all VTX files are files with no common format, the following 6 formats exist: VILTROX and whc. These files sometimes refer to male, marine, alyx, female, turret, animepatr, weedplant, hostage, armor or laser.
