The .25nv file extension is associated with Cygwin, a Unix-like environment for Microsoft Windows. The file is an internal system file rather than a document intended for direct editing.
A Cygwin terminfo file contains compiled descriptions of terminal behavior, including supported control sequences and screen, keyboard, color, and cursor capabilities. Programs use this information to communicate correctly with the terminal.
The file belongs to Cygwin's terminfo database and is read by terminal-handling software such as ncurses.
Use Cygwin's terminfo utilities to inspect this file. The infocmp command can display a terminfo entry in a readable form when the entry is installed in Cygwin's terminfo database. Opening the file in a normal Windows text editor will not produce useful readable content because it is compiled data.
There is no practical general-purpose conversion for a Cygwin terminfo file. Cygwin's infocmp utility can produce a source representation of an installed entry, and the tic utility can compile a terminfo source file back into a database entry.
