1. An information processing apparatus comprising:
circuitry configured to:
receive a plurality of files;
generate screen information for displaying a first list screen on a display, the first list screen presenting, for each of the plurality of files, a name and a time of last use of the file, and further presenting a thumbnail image of at least one file of the plurality of files in a case the at least one file is an image file;
calculate, for each of the plurality of files, an amount of time that has elapsed from the current time to the time at which each file of the plurality of files was last used;
determine, for each of the plurality of files, whether the amount of time that has elapsed is longer than a pre-set time period;
determine at least one file of the plurality of files to be an at least one unused file when it is determined that the amount of time that has elapsed since the at least one file was last used exceeds the pre-set time period;
generate screen information for displaying a third list screen on the display, the third list screen presenting, for the at least one unused file, a name and a time of last use of the at least one unused file, and further presenting a thumbnail image of at least one unused file in a case the at least one unused file is an image file;
