To enable a user to more easily set a rule relating to folder allocation and file naming at the time of filing data, such as a document scanned image and a received facsimile, and storing the file. On a user interface screen for setting a rule relating to property information that is used at the time of allocating a file to a folder for storage, at least a first area for editing the rule and a second area displaying an item a user can select are provided. The item is a unit element for a user to set a character string configuring the property information and corresponds to a character string of an arbitrary attribute a user can set. Then, the rule is created by the item selected by a user from the second area being arranged at a position designated by the user in the first area.
