The present invention relates to a synchronization system that utilizes a synchronization wizard ("PullSync") residing on a first computer device to request and receive (or "pull") data from a second computer device. The first computer device (the "syncer") copies files from shared folders on the second computer device (the "syncee") in accordance with specific pull-synchronization rules (PSRs) established on the syncer that define the scope and extent of the synchronization. This copying occurs over a network connection using existing and well-defined protocols by which one computer system is able to view and copy files from the available shared folders of a second computer system, and the PullSync wizard software needs to exist only on the first computer system (the syncer) to utilize these existing networking protocols (including existing security/authentication protocols) to selectively copy files from the second computer system.
