Description

  The present invention relates to a folder display control apparatus and method for iconifying and displaying a folder in which an image is stored, and a program for causing a computer to execute the folder display control method.

  When a folder storing images is converted into an icon and displayed as a list, thumbnail images of the images stored in the folder are displayed superimposed on the folder (see Patent Document 1). In this way, by displaying the thumbnail image superimposed on the folder, it is possible to know the outline of the image stored in the folder without opening the folder.

On the other hand, from the viewpoint of improving security, an application for locking a folder or a file has been proposed (see Patent Document 2). In such an application, when a locked folder or file icon is clicked to open, a dialog for inputting a password is opened as shown in FIG. The user enters a password in this dialog, and when the entered password is authenticated, the user can open the folder or file and check the contents.
