All about MIN Files

The MIN file type is primarily associated with OrCAD PCB Designer.

MIN	File extension: MIN
	File type:	PCB layout

What is a MIN file

MIN files mostly belong to OrCAD PCB Designer by Cadence. A MIN file is a printed circuit board layout saved in Max Interchange Notation format. Information stored in this file include footprint definition, grid, and drill coordinates. You can open this file with programs such as eM-Test Expert, Pulsonix, and OrCAD PCB Designer. Another type of MIN file is a CNC program used by Okuma CNC machines. This file can be created or edited with programs like Advanced One-Touch, EDIT, and Predator CNC Editor. MIN is also the filename extension of a geology data file saved in IAGA ASCII Exchange format. INTERMAGNET can analyze geology data saved in MIN files.

How to open MIN files

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

MIN file format:

To find out what program is needed to open MIN files, you need to determine the file format. The file format can be deduced from the file extension and the signature. However, different programs can use the same file extension. Furthermore, a file extension can be renamed incorrectly and double-clicking on it will then display an error when it is opened. When there is a problem with a file, the first step to solving it is to determine the file format. Our examination of the MIN files comes to the following conclusion:

The MIN file type is a very commonly used file extension and includes many different file formats. But the following two file formats are common:

• 6% of all MIN files are based on the well-known UTF-8 file format. UTF-8 is the World Wide Web's most common character encoding for Unicode. UTF-8 files can be viewed with any text editor. These files start with the 3 bytes  (hex: EF BB BF), the so called byte order mark (BOM). The contents of these files can even be read by a human. MIN files can be up to 5 KB in size, but are often around 1 KB - 2 KB. Several words can almost always be found in the files, e.g. DEF WORK, DRAW, END, CLEAR, M219(TURRET AIR ON), EMPC, PS LC, [0,0], [3,121],0, PS LC, [0,0], [3,151] and (**** LOAD NEW PART ***).
• 6% of all MIN files use the same file format, which can be identified by the letters "(EMPC" at the beginning. These files are plain text, which means they can be viewed with any text editor such as Windows Editor, Nano for Linux, and TextEdit for macOS. Most of these files are 1 KB to 2 KB in size. The files contain the following words: EMPC, CLEAR, DEF WORK, DRAW, END, M219(TURRET AIR ON), (***** NEW PART *****), (***** START OF PROGRAM *****), PS LC, [0,0], [3,172],0, SPINDLE and VZOFZ. The file name P0001.MIN is typical for these files.

All other MIN files (88%) have no uniform format, often, for example, Okuma CNC program, JSON, Format, WPC, MPC and NTOP. Tagged as resource, strings, plugin, json, dmin, exported, okuma or vmin.
