If you've never run File Browser, you will need to create the database.

This command is used to start up the server. By default it starts listening
on localhost on a random port unless specified otherwise in the database or
via flags.
Use the available flags to override the database/default options. These flags
values won't be persisted to the database. To persist configuration to the database
use the command 'filebrowser config set'.`,
