Since Falcon 3, the Falcon Factory has been revised and the soundbank file is now named Falcon Factory rev2.ufs.
Note that the Falcon Factory rev2 is not backward compatible with projects made with previous versions of the Falcon Factory.
You can still keep the old Falcon Factory file in a separate folder for your old projects. Simply add this folder to the Soundbank paths list in the Preferences in Falcon by disabling 'automount' and enabling 'indexed'. By doing so, the legacy Falcon Factory will only mount in Falcon for projects that use it.
