<P>PROBLEM TO BE SOLVED: To make file attributes to be common in two different operating systems of a file system. <P>SOLUTION: In the two different operating systems of the file system, a difference set of a set X by a set Y is mapped to a difference set of the set Y by the set X when X is set to be the set of the file attributes on a native operating system of the file to be used and Y is set to be the set of the file attributes in the operating system to be operated. The set Y is except for a case when it is included in the set X. Thus, the file attribute which cannot originally be use can be used and the file of the prescribed file system can be treated on the different file system. Consequently, mutual operability can be improved and the file can appropriately be treated. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
