In a case where a user adds or deletes a separator to or from an automatically generated file name or the like, it is made possible to automatically generate a file reflecting the presence/absence of a separator at the time of transforming a scanned image of a document of the same kind into a file from next time. In a case where a document similar to a document scanned in the past is scanned, based on results of learning including the presence/absence of a separator, a property for a document scanned this time is generated automatically and presented.
