Method and apparatus for automatically updating a data file from a network

摘要

A computer-based system and method of updating and viewing an electronic slide show presentation is disclosed. The method includes storing a local version of the slide presentation file and an indication of the most recent update to the slide presentation. When a user launches the local slide presentation, the date of the most recent update to the slide presentation is retrieved, and used to determine whether a new update is advisable. A dialog window queries the user as to whether to perform an update of the slide presentation. If the user responds affirmatively, the slide presentation program automatically retrieves a version of the slide presentation from a remote computer on a network. After updating the local version of the an slide presentation file, an electronic slide show is automatically launched utilizing the remote version retrieved from the network.
