Opening an X File

The X file type is primarily associated with DirectX.

X	File extension: X
	File type:	3D object

What is an X file?

X files mostly belong to DirectX by Microsoft. X file extension is mainly associated with the X file format used to save DirectX objects. Contents of DirectX object files includes geometry meshes, textures, animations, and material information used by a 3D model in a game. The X file format was introduced with version 2.0 of DirectX, the media technology used to manage and render audio, video, games, and 2D/3D graphics on Windows computers. Magic3D Easy View, a computerized stage-lighting planning and simulation software uses the X file format to store 3D objects. The X file format is also used to store Lex programming language source code. X file extension was used by several outdated formats; Human68k, a an obsolete operating system stored program executable data in X files, X11, a Unix GUI application stored its server import image in an X file; and SuperDisk, an obsolete archiving application stored self-extracting archives as X files.

How do you open X files?

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

Programs that open and convert X files:

DirectX by Microsoft
See the previous paragraphs to learn more about the main application. X files are often referred to as DirectX 3d images because this type of file is primarily created or used by this software.
Amapi (3D model) by Smith and Micro
Amapi was a NURBS and polygonal 3D surface modeling software that was widely used in architectural, interior, product, and industrial design. Some versions of the program stored 3D models in X files. This file format is classified as 3D Image.
AVS (bitmap) by Stardent
AVS, short for Application Visualization System is an obsolete software package for dynamically connecting software modules in a ways that allow the creation of data flow networks used in scientific computation. The program stored bitmap images in X format. This file format is classified as Raster Image.

FPS Creator (3D model) by The Game Creators
FPS Creator is a First Person Shooter game development program that allows users with no programming or 3D modeling knowledge to make their own games. The compiled game is distributed as a standalone EXE file whereas the 3D models used in the game have X file extension. This file format is classified as 3D Image.
LEX (program source code) by Mike Lesk and Eric Schmidt
Lex is a lexical analyzer generation program for Unix and Unix-like operating systems. It works by reading input streams which it then uses to output source code implementing the C programming language lexer. This file format is classified as Developer.
REXX (script) by IBM
REXX (REstructured eXtended eXecutor) is an interpreted programming language used as a macro and scripting language for reports generation and data processing purposes. Files containing a REXX script had X filename extension. This file format is classified as Developer. Related links: Wikipedia REXX Page
SuperDisk (self-extracting archive) by Alysis
SuperDisk is a file compression software compatible with several Mac operating systems. Self-extracting archives created with this program have X filename extension. This file format is classified as Compressed.
XBLite (program source code) by David Szafranski
XBLite is a BASIC programming language program compiler developed to provide an XBasic dialect only used on Windows. This compiler stored program source code in X files. This file format is classified as Developer.
Xview (3D object) by Oracle
Xview is a widget toolkit used to provide an OPEN LOOK user interface on X Windows System software. The program stored 3D objects used to create DirectX scenes in X files. Xview has been discontinued but its X files can be opened with third-party software such as XnView. This file format is classified as 3D Image.

X file format:

If you can determine the file format, the associated program can also be determined. The first characters in a file identify the file format, for example, HTML files start with the bytes <html>. Frequently, however, one file extension is used by different programs for different file formats, and one file format for different file extensions. So you need a detailed analysis of a file to find out the format and the associated program. Our analysis of the X files produces the following result:

The X file extension is quite widespread and includes various formats for various programs. The two most popular formats are as follows:

60% of all X files belong to Microsoft Direct3D Object. X files are between 5 KB and 1 MB in size. The file type was developed 20 years ago and is still in use today. The keywords xof 0303txt 0032 and template are typical for these files. These files are attributed to boat, body, avatar, gust, mesh, user, defence and female.
6% of all X files save the data in ELF file format. ELF is the abbreviation for Executable and Linkable Format and is the standard binary format on Linux and Unix. The content consists of illegible binary data, which can only be read and interpreted by the associated programs. X files can be up to 250 MB in size, but are often around 12 KB - 4 MB. Files like these are about proj.

All other X files (34%) have different formats, the following 16 formats can be found: Magic 3D Easy View object, Panzer Elite Action game data archive, ZIP, PDF, Java, JFIF, DOC, EXE, GZIP, NORK, cscipy, KSM and iDN. Files like these are sometimes linked to lung, striker, sorted, weapon, model or unit. You can get all the details of your X file by dragging it onto this page or by clicking the button "Choose your .x file to view this image" above.

an x 3D object is a special file format by Microsoft and should only be edited and saved with the appropriate software.

How to solve problems with X files

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