Abstract: PROBLEM TO BE SOLVED: To obtain the file system which is more flexible and improved as a file system having an external structure of fixed size by including at least one part wherein another file system arranged for dynamic storing operation. SOLUTION: This file system is the file system 8 having the external structure of fixed size and includes at least the 1st file 12 wherein another internal file system is arranged for dynamic storing operation. A file system driver is dynamically constituted by using a 2nd file containing user information such as the size, owner information, and key field of the file system 8. This nesting type file system 8 can be edited by being accessed sufficiently dynamically without affecting a basic ISO file layout, i.e., the external fixed structure of an external file system.
