PROBLEM TO BE SOLVED: To provide an information processor capable of reducing the capacity of a random writing and reading memory required for executing a program on a read only memory by using a virtual storage function; and to provide a file management method. SOLUTION: The information processor uses the virtual storage function for executing the program and has: a file management function managing a file 31 on the read only memory 3; a table generation function generating a table associating the physical address of the program contained in the file on the read only memory 3 with the virtual address of the program; and a program execution function obtaining the physical address corresponding to the virtual address of the program on the read only memory 3 from the table in executing execute the program, and executing the program on the read only memory 3.
