The invention relates to a file copy control method and system, and the method is realized based on at least one server side and at least one client side, and the server side sets a file copy controlstrategy and issues the strategy to the client side; the client monitors a file copy event in real time through a Windows IFS bottom drive technology according to the file copy control strategy and generates a log; and the client uploads the log to the server in real time. Through the Windows IFS bottom layer driving technology, all actions of copying files to mobile equipment can be monitored inreal time, and file names and the number of copied files are obtained. Meanwhile, early warning of day, week and month copying of each user and the number of suspended files can be flexibly set, so that copying requirements of different clients are met.
