.cn1 File Extension

Developer: MITRE
File type: CNR Modem Initialization Data File
You're here because you have a file that has a file extension ending in .cn1. Files with the file extension .cn1 can only be launched by certain applications. It's possible that .cn1 files are data files rather than documents or media, which means they're not meant to be viewed at all.

what is a .cn1 file?

CNR modem initialization data files are affixed with the .cn1 extension, and these CN1 files are stored in file compression and encoding specifications developed by MITRE. MITRE created the CN1 format for the CNR Init Data Parser software, particularly to be used as data files by this application, which was also developed by MITRE. This CNR (Combat Net Radio) data parser application stores initialization data fields integrated with formatting atributes in these CN1 files, and the data in these CN1 files are used for MIL-STD-188-220 CNR modems connected to Microsoft Windows-based systems. Exactly four hexadecimal characters comprise each line of code stored in these CN1 files, and these CN1 files may contain many lines of code. Files appended with the .cn1 extension are mainly used for the development of automated systems implemented into networking initialization processes of tactical military programs. Elements and attributes like bearer waveform and program header among other tactical networking modem details are found in a CN1 file.

how to open a .cn1 file?

Launch a .cn1 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 .cn1 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 .cn1 files aren't yet associated with it. In this case, when you try to open a .cn1 file, you can tell Windows which application is the correct one for that file. From then on, opening a  .cn1 file will open the correct application.

MITRE CNR Init Data Parser

MITRE CNR Init Data Parser

The .CN1 file format is developed by the MITRE Corporation for its Combat Net Radio (CNR) data parser applications to be utilized as data files which is also a MITRE property. It contains layout initialization data fields for systems using MIL-STD-188-220 CNR modems integrated with Microsoft Windows based systems, and it is saved in a file compression and encoding specifications, an ASCII text format as a series of lines, each of which contain four hexadecimal characters. CN1 files are generally intended for use in automating the networking initialization process for tactical military applications. It has data elements and attributes for tactical networking modems, such as the application header, the bearer waveform, and other application-specific parameters. Files having a .CN1 extension can be accessed and viewed with Microsoft Windows MITRE CNR Init Data Parser application and are compatible with Windows based operating systems, such as Windows 7, Vista, XP, 2000, ME, 98, and 95.

a word of warning

Be careful not to rename the extension on .cn1 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, .cn1. 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.
