PURPOSE: A file system of a broadcasting receiver for storing a digital signal and an operating method thereof are provided to redesignate a corresponding part of a circular file stored in a time shift state as a start position of a linear file in which a current recording process is started, and to move the redesignated start position to a substantial start position by using offset information, thereby stably realizing a time shift recording. CONSTITUTION: A hard disk(10) stores a received digital signal in a circular file and a linear file. A memory(16) stores predetermined information values for each stored file. A microcomputer(7) changes features of prestored clusters(12) by changing address values of the clusters(12) from the predetermined information value for each file, redesignates a corresponding part of the circular file stored in a time shift state as a start position of the linear file in which a current recording process is started, and moves the redesignated start position to a substantial start position.
