Microsoft Direct-X SDK 3D graphics
File type category:
3d graphics, CAD-CAM-CAE file
Date updated: March 24, 2024
The x file extension is associated with the Microsoft DirectX framework and used for files that contain ASCII formatted 3D positional chart with additional graphical data for 3D environments (objects) meshes.
The x file stores Mesh data (with vertex normals, vertex uv texture coordinates and vertex colors), materials, texture references, hierarchy and object animation.
Historically, in the early 1990s the leading 3D game engine was "Rendermorphics" from Ireland. Microsoft purchased the Rendermorphics company and renamed their technology to "DirectX v3" in 1995.
The 3 Irish developers subsequentely left Microsoft a few years later in 1997, after which time the DirectX X file format did not change, except for some additions of mesh skinning prior to 1999.
How to open x file?
You can work with this X format in several graphic editors and development tools with support for DirectX.
As these files are ASCII formatted, you might also view the content using any text editor.

Stardent AVS X bitmap image
File type category:
Bitmap image file
Date updated: June 23, 2025
The x file extension is related to a very old program called Application Visualisation Software (AVS) that was sold by Stardent in early 90s.
The x file is bitmap image crated in AVS.
The AVS image format is pretty straightforward. It consists of an 8 byte header followed by a,r,g,b per pixel, ordered top to bottom, left to right. (a == alpha, r == red, g = reen, b == blue) Each colour/alpha component is 1 unsigned byte. The header simply consists of the width and height of the image, each as 4 byte unsigned integers.
Note the format assumes a byte ordering as per SGI/Macintosh/Motorola processors, if reading an AVS image from a machine with the opposite byte ordering then the appropriate byte swapping is required.

Xview object
File type category:
Various data file
Date updated: January 2, 2018
The x file extension is associated with XView, a widget toolkit from Sun Microsystems introduced in 1988. It provides an OPEN LOOK user interface for X Window System applications, with an object-oriented application programming interface (API) for the C programming language.
Its interface, controls, and layouts are very close to that of the earlier SunView window system, making it easy to convert existing applications from SunView to X. Sun also produced the User Interface Toolkit (UIT), a C++ API to XView.
The XView source code has been freely available since the early 1990s, making it the "first open-source professional-quality X Window System toolkit".XView was later abandoned by Sun in favor of Motif (the basis of CDE), and more recently GTK+ (the basis of GNOME).
XView was reputedly the first system to use right-button context menus, which are now ubiquitous among computer user interfaces. However, the claim to that first may in fact lie with Acorn Computers' Arthur operating system, which was released in 1987, though it used the middle mouse button rather than the right.
The .x files contain object data used by XView.
