<Usage example of patrol folder history (3)-Reconnection after patrol access reservation>
A usage example (3) of the traveling folder history will be described with reference to FIGS. Note that the traveling folder history in FIG. 8A is the same as the traveling folder history after the traveling access reservation in FIG. 7B.

As shown in FIG. 8A, when another electronic device A holding the folders “01_Music” and “02_Picture” is reconnected to the network 200, the lower layer folder “J” of the folders “01_Music” and “02_Picture” is displayed. The execution confirmation screen for traveling access reservation for “-POP” and “travel” is displayed superimposed on the traveling folder history screen.

Then, when the user of the electronic device 100 selects YES on the cyclic access reservation execution confirmation screen, the cyclic access reservation to the lower folders “J-POP” and “travel” of the folders “01_Music” and “02_Picture” is executed. The

In this case, there are two methods for accessing the image files in the lower layer folder “J-POP” and “Travel” for patrol access. One is a method of downloading an image file in the lower layer folder “J-POP” and “Travel” to the electronic device 100 (see FIG. 8B), and the second is a lower layer folder “J-P”. This is a method of pulling out image files in “POP” and “Travel” (Pull) and executing a slide show (see FIG. 8C).

As shown in FIG. 8B, when the cyclic access reservation for the lower layer folder “J-POP” and “travel” is executed, the files in the lower layer folder “J-POP” and “travel” are downloaded. . In this case, a character “GET!” Indicating that a file in the lower layer folder “J-POP” is being downloaded is superimposed on the icon of the lower layer folder “J-POP”.

As shown in FIG. 8C, when the cyclic access reservation to the lower layer folder “travel” is executed, a slide show of a plurality of files (for example, image file 3) in the lower layer folder “travel” is executed. If the user touches the stop button displayed on the traveling folder history screen, the slide show is stopped.

As described above, electronic device 100 according to the present embodiment can make a cyclic access reservation for a folder that was previously inaccessible, and another electronic device that holds the folder has reconnected to network 200. Sometimes, the files under that folder can be automatically downloaded or a slide show can be executed. Furthermore, electronic device 100 according to the present embodiment can update the folder structure image by performing a cyclic access again after executing a cyclic access reservation to a folder that has been inaccessible in the past.

In addition, although the object of the patrol access reservation is limited to the folder that could not be accessed in the past, it is not limited to this. Electronic device 100 according to the present embodiment can be executed, for example, by a timer that incorporates a cyclic access reservation for a currently accessible folder at a predetermined time.
