.x file type #3: Chemical modeller output data

An x file extension is related to the Chemical modeler output file format.

Further details:

The x file extension is used for XMOL molecule model files. Used in cheminformatics applications and on the web for storing and exchanging 3D molecule models.

Plain text tabular format. Represents a single chemical compound. Stores atomic coordinates and meta-information. Does not store chemical bond information. Developed in 1990 at the Minnesota Supercomputer Center.

.x file type #4: Human68k operating system executable

An x file extension is related to the executable files of programs for Human68k operating system.

Further details:

The x file extension was also used in Human68k, an MS-DOS like operating system for Sharp Corporation's personal workstation X68000. Developed by SHARP and Hudson Soft.

The x file stores program executable data.

.x file type #5: Microsoft Direct-X SDK 3D graphics

Files with x file extension might also be found as ASCII graphics files from DirectX development tools.

Further details:

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.

.x file type #6: Stardent AVS X bitmap image

An x file extension is related to the Stardent AVS X bitmap image file format.

Further details:

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.

.x file type #9: Xview object

An x file extension is related to the XView, a widget toolkit for X Window System. An x file stores object.

Further details:

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.

What is the meaning of a file extension?

File extensions are characters that appear after the dot in a computer file's name. For example, the file "unknown-file.x" has the file extension "x". This is used to identify which program should open the file or what file type it is.
File extensions help you organize and manage files. They provide a quick and easy way to identify and associate the file type with the appropriate software.
