The fnw file extension is associated with FLARENET, a flare system design and rating application developed by AspenTech for Microsoft Windows.
An fnw file contains the model data used by FLARENET. It is a native data file for the application rather than a general-purpose document format, so its contents are normally interpreted and edited by FLARENET.
Open an fnw file with FLARENET on Microsoft Windows. Use the application's file-opening command and select the file if it is not opened by double-clicking.
Open the fnw file in FLARENET and use the application's built-in save or export options when model data must be transferred to another supported format.
