An electronic apparatus includes: a storage device; an application program execution circuit that executes an application program for managing input/output of data to/from the storage device; a counter control circuit that counts the number of execution of the application program and records a time and date of the execution; a retention period setting circuit that obtains execution frequency of the application program based on the time and date recorded by the counter control circuit, and sets a retention period of the data stored in the storage device depending on the obtained execution frequency; and a data deletion circuit that deletes the data from the storage device when the retention period has passed.

An image forming apparatus records identification information of an external memory and identification information of a scan job as a log when the external memory is attached to start the scan job. When the external memory is removed in the middle of the scan job, scan data is temporarily saved together with the identification information of the job. When the removed external memory is attached, for example, in a ready state, log data is referred to determine whether the external memory is that removed in the middle of the job and whether the scan data associated with the external memory is saved. When it is determined that the scan data is saved, the scan data is saved in the external memory.

A disclosed managing apparatus and image forming apparatus management system ensure confidentiality of information in an image forming apparatus while usability is maintained. An image forming apparatus acquires IC card identifying information with an IC card reader. A management server acquires a user ID associated with the acquired IC card identifying information and use limit information concerning use of the image forming apparatus. A process is performed in the image forming apparatus in accordance with the use limit information.

An electronic device, such as a digital camera, includes a deletion mode whereby a camera/electronic device user can delete captured images or data files that have already been transferred in order to make room in the electronic device or digital camera memory for capturing further images. In one embodiment, a digital camera keeps track of which images have already been transferred to an external storage device and presents those to the user as potential images to be deleted. In another embodiment, the user is presented with a delete all transferred images which when selected deletes all the captured images that have already been transferred. In still another embodiment, deletion criteria are used to prioritize which images are deleted first.
