Abstract:
1. A file management method in a web storage system, in which files of a specific type are managed by a file management system which provides a web storage service for storing a file created by the first user terminal connected through a network, the method comprising: a first step of transmitting and installing a file management client program in the first user terminal by a file management server included in the file management system, if the first user terminal connects to the file management system through a LAN or an Internet; a second step of starting file monitoring on the first user terminal by the file management client program, after the file management client program sets and stores a file management policy that will be applied to the first user terminal; a third step of transmitting a file having an extension set as a monitoring target in the file management policy to the file management system and deleting the file from the first user terminal by the file management client program, if the file management client program finds the file while monitoring the first user terminal; a fourth step of storing the transmitted file in a file DB and recording information for searching for the file using a DBMS by the file management server; a fifth step of allowing the first user terminal to connect to the file DB through a network file system driver and open a specific stored file by the file management server, if the first user terminal connects to the file management system and requests the specific file; a sixth step of performing a process of updating and storing the file in one transaction and storing details of the update in the file DB by the file management server, if the first user terminal updates contents or attributes of the file and requests to store the updated file a seventh step of storing approval application information in an approval information DB by a take-out information management server, if the file management system receives an application for taking out a specific file through a USB memory, from the first user terminal where the file management client program is installed; an eighth step of updating the approval information DB, if a manager approves take-out of the file through a manager terminal; a ninth step of connecting to the file management system and transmitting information on approval and information on a target file to be copied, if the USB memory is connected to the first user terminal and a worker clicks a file download and USB memory store button; a tenth step of confirming whether or not the approval is normally obtained and transferring information on a location where the file is stored to the file management client program by the take-out information management server; an eleventh step of downloading and storing the file into the USB memory by the file management client program, if the file management server unlocks security (locking) locked on the file; and a twelfth step of locking the security again for the corresponding file by the file management server, if take-out of the file is completed.
