Abstract
There are disclosed a method and system for managing a file that allows an operator to easily select, specify, and manage a multimedia file (including audio data, text, still image, moving image, etc.) via a display screen. The type of a file is identified. If the file is an audio data file, then an icon is generated with an image representing an amplitude waveform or a frequency distribution waveform of the audio data, or, the icon is generated with an image including a color or a pattern preassigned to the frequency distribution or both. If the file is a text file, then an icon is generated with an image representing an arbitrary area of an arbitrary page of the text file. If the file is a still image file, then an icon is generated with an image obtained by reducing an arbitrary area of the still image. If the file is a moving image file, then an icon is generated with an image obtained by reducing an arbitrary area of an arbitrary scene of the moving image.
