What is an FC file?
Settings file used by OpenText FirstClass, an emailing and conferencing application that enables collaboration and communication between users; contains login data referenced by FirstClass to connect users to the server; may store resources, such as forms, pictures, icons, and sounds, that customize the FirstClass interface.
NOTE: If there is no settings data in the file, it will be given the .REZ extension, which means that the file only holds resources that customize the interface.
