This option appears only when you are creating a new classifier. Configure settings on this page if you want to use this classifier in policies on a disconnected network. Here you export this classifier to a network location. Later, you can copy it to the other network (using an external disk, for example) and import it using the Import option on the File Fingerprinting toolbar. See Imported fingerprinting for details. (The disconnected network must have a management server as well.)
