A system and method for managing distributed files includes a central sub-MIS system (9), branch sub-MIS systems (7, 8), and an electronic communications network connecting all sub-MIS systems. Each sub-MIS system comprises at least one client computer (71, 81, 91), an application server (72, 82, 92) and a database server (73, 83, 93). When the network is available, each client computer of each branch sub-MIS system is connected with the application server of the central sub-MIS system 9 for opening new files online. The database server of the central sub-MIS system 9 replicates newly-opened file information to the database servers of all branch sub-MIS systems. When the network is unavailable, each client computer of each branch sub-MIS system can open new files offline. When the network becomes available, a recovery program in the application server of each branch sub-MIS system initiates change of each offline-opened file into an online-opened file.
