What is the GFC file format?
A file with the .GFC extension is a file known as Patton&Patton Flow Charting 4 Flowchart. This format is associated with Patton&Patton.
The reliable way to open a .GFC file is with software that recognises this exact format, rather than guessing from the file name. If you are not sure what created a file, our file identifier can read its first bytes and name the real format, even when the file has been renamed.
We are still gathering the list of programs that open .GFC files. A fully verified, hand-written description of this format is being prepared; until then, the details on this page are drawn directly from our database.
