Abstract

An information processing device is disclosed that is of improved operability and is able to efficiently predict operations to be conducted by a user on various kinds of electronic files. The information processing device includes a selection candidate presentation unit for presenting candidates of selection functions when an icon is selected, an electronic file information acquisition unit for acquiring electronic file information, and a storage device which includes a parameter table A, an operations history table B, and an electronic file information table C. Concerning the electronic file selected by the user, the electronic file information acquisition unit obtains the electronic file ID, and the selection candidate presentation unit predicts a number of operations to be executed based on the electronic file information, the parameter table A, and the operations history table B, and presents the selection candidates to the user.
