Abstract
A storage medium stores a large number of data sets or files as grouped in a smaller number of data groups or directories, each data group containing a plurality of data sets. On a control panel is provided a display screen, and are also provided a plurality of group call buttons to be individually allocated for the respective data groups and a plurality of data set designating buttons to be individually allocated for the respective data sets. When the user actuates an intended one of the group call buttons, identifying names or marks of the data sets of the called group are listed in a display screen for a further selection of the intended data set from among the listed group by user's actuation of an intended one of the data set designating buttons. This enables an easy and speedy selection of a particular intended data set from among a large number of data sets.
