.xyz File Extension

Developer: Geoff Hutchison
File type: Avogadro Data Files
You're here because you have a file that has a file extension ending in .xyz. Files with the file extension .xyz can only be launched by certain applications. It's possible that .xyz files are data files rather than documents or media, which means they're not meant to be viewed at all.

what is a .xyz file?

There are multiple applications associated with the .xyz file extension, and most of these are data management programs for chemical information. the .xyz files used by these programs are implemented to make these applications more useful. These .xyz files contain molecular model descriptions, including atom numbers, element symbols and X, Y, and Z coordinates. These .xyz files are usually created and saved in the plain text format. The .xyz file extension implemented by these programs is also used to provide data model examples. Various applications can be used to open these .xyz files, such as Avogadro. Likewise, the file extension is also used by programs that can be used for planetary visualization and simulation. In these applications, these .xyz files are used as storage of information like timestamps and a list of positions.

how to open a .xyz file?

Launch a .xyz file, or any other file on your PC, by double-clicking it. If your file associations are set up correctly, the application that's meant to open your .xyz file will open it. It's possible you may need to download or purchase the correct application. It's also possible that you have the correct application on your PC, but .xyz files aren't yet associated with it. In this case, when you try to open a .xyz file, you can tell Windows which application is the correct one for that file. From then on, opening a  .xyz file will open the correct application.

The Avogadro software is used in computational chemistry, molecular modeling, bioinformatics, material science and other sciences related to it. With its rendering and plugin architecture, it functions as a molecular editor and provides visualizer designs. This software is free and an open source which is available under GNU GPL. It has international translations, pages can be translated to French, German, Italian, Spanish, Chinese and Russian, the Avogadro team is still working on incorporating more language translations. This program is built for students and advanced researchers and supports computation and multi-threaded rendering. Developers are also welcome, with the program's plugin architecture that includes, tools for rendering and interactivity, commands and Python scripts. Avogadro features an Open Babel, it is a chemical toolbox with all the languages of chemical data. It is a open, collaborative language which means that anyone is welcome to search, convert, analyze, or store data from molecular modeling, chemistry, solid-state materials and biochemistry. the Open Babel has 110 chemical File formats and has been downloaded for more than 164,000 times.


Celestia is a real-time, photo realistic, 3D viewing of the solar system including the galaxy and the universe. It runs in multi-platform and is used in the study of astronomy. Museums, planetariums, schools use this as a tool for teaching astronomy and also as a visualization tool for space mission designers. It displays Hipparcos Catalogue (HIP) which has 118,322 stars, and users can choose to display the number of stars visible on the screen ad draw them in different styles. Celestia uses the VSOP87 theory of planetary orbits that provides a display of the orbital paths of planets which includes extrasolar planets, dwarf planets, asteroids, comets, moons, spacecraft and artificial satellites which also includes a solar and lunar eclipse finder. Users can fly through the Celestia universe at any speed ranging from 0.001 m/s to millions of light years/s using simple keyboard controls which allows orbiting stars, moons, planets, other space objects and other track space objects like spacecraft, asteroids, comets as users pass by through nebulae and irregular, spiral and elliptical galaxies.

a word of warning

Be careful not to rename the extension on .xyz files, or any other files. This will not change the file type. Only special conversion software can change a file from one file type to another.

what is a file extension?

A file extension is the set of three or four characters at the end of a filename; in this case, .xyz. File extensions tell you what type of file it is, and tell Windows what programs can open it. Windows often associates a default program to each file extension, so that when you double-click the file, the program launches automatically. When that program is no longer on your PC, you can sometimes get an error when you try to open the associated file.
