What is an FM file?
An FM file is a document created with Adobe FrameMaker, an application used to author, enrich, manage, and publish technical documentation. It stores information about the structure of a page that is set to be published for print or the web. FM files may store pages that are meant to be individually published or published as part of a FrameMaker book (.BOOK file).
NOTE: FrameMaker only supports .FM documents created in FrameMaker 3 or later.
