Abstract

A method and system for associating, synchronizing and reconciling files. Associated files are synchronized and their synchronization status reported. Based on the synchronization status, the operating system recommends a preferred reconciliation action. Furthermore, file conflicts are recognized and an application interface for computer applications is provided to allow conflicting files to be merged.
