Cygwin uses the GNU Info documentation system for manuals and other reference material. An .info-4 file is typically the fourth numbered part of an Info document, accompanying a main .info file and other numbered parts.
The file contains documentation data for the Cygwin environment and its installed tools. It is not usually a standalone application or user-created project file; the Info reader uses the related files together to present the complete manual.
This format is associated with the Cygwin project on Microsoft Windows. Numbered Info files remain a normal way to store split Info documentation in Cygwin packages.
Open the related main .info file with the Cygwin Info reader. The reader should locate and use the numbered .info-4 part when all parts are in the same directory; the Cygwin info command may need to be installed.
If the Info reader is unavailable, a text editor can usually display the file's documentation content, although links and navigation between the numbered parts may not work correctly.
An .info-4 file is a component of an Info document and normally has no useful standalone conversion. Keep it with the related .info file and other numbered parts and read it with the Cygwin Info reader.
For a different presentation, the documentation can be copied, printed, or exported from an appropriate Info-reading tool. Converting only this numbered part may produce incomplete documentation.
