The .n file extension is associated with Cygwin, a collection of GNU and open-source tools that provides functionality similar to a Linux environment on Microsoft Windows, developed by Red Hat, Inc.
A .n file contains data used by Cygwin's manual-page system and related Cygwin tools. Cygwin uses these files as part of its installed manual data on Microsoft Windows.
Open the file in a Cygwin installation with Cygwin's manual-page tools, where it can be used as part of the installed man data. It is not normally opened as a standalone document.
If the file contains readable text, a text editor can display it, but changing it may prevent Cygwin's manual-page tools from using it correctly.
A Cygwin .n file is internal man data and does not have a useful general-purpose conversion format. It should normally be left in place for Cygwin to use.
To obtain readable documentation, use Cygwin's manual-page tools rather than converting the data file.

Neko is a multiplatform virtual machine and programming-language platform. The Neko compiler translates Neko source code into bytecode and saves the result as an n file.
The bytecode can be executed by the Neko VM rather than directly by the operating system. Neko is available for Windows, macOS and Linux. The n file format is a runtime format, so the original Neko source code is normally required if the program needs to be modified or rebuilt.
Install Neko for the appropriate platform, then run the n file with the Neko virtual machine. The Neko runtime is available for Windows, macOS and Linux.
An n file is an executable bytecode file, not a document intended for editing in a text editor.
There is no usual conversion from Neko bytecode to another executable format. To create a new n file, compile the original Neko source code with the Neko compiler.
Converting an n file back to the original Neko source code is not a supported, lossless conversion.
