.prm File Extension

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

what is a .prm file?

PRM files are parameter files categorized as settings files because they are files that different kinds of applications use to input data parameters. PRM files are normally saved in plain text wherein a key-value structure is used. This structure consists of a line with the name of the parameter and the value. In other words, PRM files contain parameter settings and these indicate what the user wants to be done by the program. A lot of applications using PRM files are as follows: GSAS, CodeWarrior, Red Hat Enterprise Linux (RHEL) operating system installer, IBM ILOG CPLEX Optimization Studio, Gurobi Optimizer, and P300 Classifier GUI. GSAS runs on Windows, MAC and Linux and this application refines structural models to x-ray and neutron diffraction data. The Gurobi Optimizer also runs on Windows, MAC and Linux and it is an application used for quadratic programming, mixed-integer linear programming, linear programming, quadratically constrained programming, etc.

how to open a .prm file?

Launch a .prm 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 .prm 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 .prm files aren't yet associated with it. In this case, when you try to open a .prm file, you can tell Windows which application is the correct one for that file. From then on, opening a  .prm file will open the correct application.

Gurobi Optimizer

Gurobi Optimizer

Gurobi Optimizer is a mathematical programming solver from Gurobi Optimization, Inc. The program provides users with tools to optimize solutions for quadratic programming (QP), quadratically constrained programming (QCP), mixed-integer quadratic programming (MIQP), mixed-integer quadratically constrained programming (MIQCP), mixed integer linear programming (MILP), and linear programming (LP). The latest version (5.1) features optimization algorithms with fast and proven optimality on mixed-integer programming models. It has flexible interfaces and supports a large number of programming languages like matrix-oriented interfaces for R, C, and MATLAB, and object-oriented interfaces for C++, .NET, Python, and Java. It provides maximum productivity to users by supporting links to modeling languages like AMPL, MPL, GAMS, and AIMMS, and links to Excel through Risk Solver Platform and Premium Solver Platform. Significant improvements on mixed-integer programming (MIP), numerical robustness, user control of the random number seed, and updated platform support are some of the enhanced features in the latest version. The supported platforms are Windows 8, Mac OS, X, Python 2.7, SuSE 12, and RHEL 6.3.

a word of warning

Be careful not to rename the extension on .prm 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, .prm. 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.
