What is a MOD file?

A MOD file is a music module file saved in the standard music module format, which originated from the Amiga module format. It contains note patterns (similar to a .MIDI file) and sound samples, representing different instruments that are played back according to the notes. MOD files are typically used for background music in video games and in the "demoscene" computer art subculture.

The Amiga module format was originally developed by Karsten Obarski and released with the Ultimate Soundtracker software for the Commodore Amiga system in 1987. As music trackers began supporting the format, especially on PCs in the 1990s, other developers released variations of the MOD format.

Originally, the MOD format only supported four audio channels and sixteen different instruments. However, recent MOD variations have increased the number of supported channels to 32 and supported instruments to 31.

The sound samples within a module are assigned to different tracks and are played back according to the notes in the score. A MOD module also includes a list that tells the application playing the module the order the patterns are to be played.

NOTE: MOD files may be created by various MOD trackers, including FastTracker, StarTrekker, Noise Tracker, MilkyTracker, and Cog.

How do I open a MOD file?

You can open a MOD file with various audio players, such as Nullsoft Winamp (Windows), VideoLAN VLC media player (multiplatform), Schism Tracker (multiplatform), and MikMod (multiplatform). Some audio players that support MOD files may no longer be developed and not work on modern operating systems.

On an Android device, you can play MOD files with Xmp Mod Player, and on iOS devices, you can use PureModPlay or VividTracker to play MOD files.

You can also convert MOD files with various applications, such as MilkyTracker (Windows) and Cog (macOS).

What is a MOD file?

Software module used by GRUB (GRand Unified Bootloader), a boot loader used for loading multiple operating systems; stores a GRUB module and is loaded by GRUB 2 dynamically only if needed for the particular boot process.

More Information

GRUB 2 was slightly redesigned to be modular. This design allows a smaller footprint for the boot loader since only required modules are loaded.

GRUB MOD files are located in the /boot/grub/ or /boot/grub2/ directories.

What is a MOD file?

Compiled program file written in the Fortran programming language; created for each module declaration within the Fortran source code; groups related procedures and data together in a single file, which can be referenced other program units.

More Information

Fortran MOD files are "intermediate" files and are not meant to be opened manually. However, they may be referenced by Fortran compilers, such as those listed below.

What is a MOD file?

Model file used to compute complex, large-scale mathematical problems; contains variables (parameters, and sets), a function, and constraints written in AMPL (A Mathematical Programming Language) code; appears as linear, nonlinear, quadratic, mixed-integer, and other problem types; includes comments, which must be prefaced with a "#."

More Information

To load your MOD file, e.g., example.mod, type model example.mod; if it's located in your "amplcml" folder with your sw.exe file. If your example.mod file is located in a different location you'll need to include the path. Type something like this (if using Windows): model C:Usersexample.mod;. After successfully loading your MOD file, type solve; to solve the problem. Then if you want to display any of your results, type display and whatever results you want displayed. Remember to always end your line with a ;.

An example of a MOD file:

var XB;
var XC;
maximize Profit: 25 * XB + 30 * XC;
subject to Time: (1/200) * XB + (1/140) * XC <= 40;
subject to B_limit: 0 <= XB <= 6000;
subject to C_limit: 0 <= XC <= 4000;

What is a MOD file?

Go.mod is a file that tracks a Go module's dependencies. It contains plain text that specifies a module's name, Go version requirements, and contingent modules. Each Go module is linked to a corresponding go.mod file.

More Information

Go is an open-source programming language originally developed at Google. It is similar to C except that it includes additional features. Go is also sometimes referred to as Golang.

Modules are Go's primary building blocks. Each Go module contains one or more functions that can be called by other modules. To ensure that each module's required Go versions and code dependencies are tracked accurately, Go produces a go.mod file for each module. Each module's go.mod lists:

  • The module's name, after the module directive
  • The module's required version(s) of Go
  • The modules that the module is dependent upon

More complex modules may include additional information in their go.mod files. For example, developers can use the exclude command to prevent their module from using a certain version of a contingent module, or they can use the replace command to load a different version of a contingent module. Developers can also include comments by prefacing the comments with //.

How do I open a MOD file?

You can open go.mod in any text or source code editor, such as Microsoft Visual Studio Code (cross-platform). However, you should not manually edit go.mod, as doing so may cause the file's associated Go module to function incorrectly.

If you want to make changes to a go.mod file, you should do so using the go mod command and associated sub-commands, such as go mod edit or go mod tidy.
