What is an XVG file?

XVG files mostly belong to GROMACS. XVG files are text-based simulation output files used primarily by GROMACS in molecular dynamics studies. They hold numerical data—such as time series, energy values, and other measurements—arranged in columns.
Key details sourced by FilExt.com:

GROMACS simulation: These files log detailed data from simulation runs. For more specifics, refer to the GROMACS manual.

Grace plotting: A variant of the XVG format is structured for the Grace plotting tool, which helps visualize simulation data. Details are available here.

GMD simulation: Some XVG files also represent output from GMD simulation modules within the GROMACS environment.

FilExt.com note: The format is plain and editable. You can open these files with a basic text editor or import them into specialized graphing software like Grace to analyze and plot your data.

How to open XVG files

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

Molecular dynamics. The Mime types used with this association are: xvgr/xmgr.

XVG file extension format:

Each file has a definite file format, that is, how the stored data is arranged in the file. The first characters in a file identify the file format, for example, HTML files start with the bytes <html>. If the file extension or signature does not match the file format, errors will occur when opening or editing the file. So you need a detailed analysis of a file to find out the format and the associated program. In the following you will find our evaluation of the XVG files:

The XVG extension is quite commonly used. The file itself mainly uses a defined XVG format. The file formats most commonly found in XVG files are:

90% of all XVG files have the same signature # This file was created . If you open these files in a text editor, you can view and read the content yourself. XVG files can be up to 670 MB in size, but are often around 2 KB - 260 KB. This file type is new and state-of-the-art. The following keywords are characteristic: created, This file, # Created by, Executable, Data prefix, gromacs, local and GROMACS - gmx energy. Some examples of file names are potential.xvg or rmsd.xvg. Files like these are sometimes connected to temperature, density, gyrate, energy, rmsf, pressure, xtal and protein.
1% of all XVG files use the same file format, which can be identified by the letters " " at the beginning. The contents of these files can even be read by a human. The files are 13 KB to 6 MB in size, with a median of 6 MB.

All the rest of the XVG files (9%) have different formats. Often described as total, dist, temp, distance, hbnum or hbond. Drag & drop your file here to see the file format and a preview of your XVG file!

How to solve problems with XVG files

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