File Storing Method, File Storage System, and Computer Readable Recording Medium Stored with Computer Program Executable on Master File Combination Device

A file storage system comprising:

• a specific file generating unit for generating a specific file to be stored;
• an additional information generating unit for generating additional information concerning said specific file;
• a specific file storage unit for storing said specific file and said additional information;
• a master file storage unit for storing a master file with which said specific file can be combined;
• an acquiring unit for acquiring said specific file and said additional information from said specific file storage unit:
• an identification unit for identifying type information that indicates a type of contents of said specific file from said additional information;
• a judgment unit for judging whether or not a master file that corresponds to said type information exists in said master file storage unit;
• and
• a combination processing unit for combining said specific file with said master file and adding identification information, for identifying said specific file, identified from said additional information to said master file as reference information for referencing said specific file in said master file, if it is judged that a master file that corresponds to said type information exists.

A computer readable recording medium stored with a computer program executable on a mater file combination device for combining files, said computer program causing said master file combination device to execute a process comprising:

• (a) acquiring a specific file to be stored and additional information concerning the specific file;
• (b) identifying type information that indicates a type of contents of said specific file from said additional information;
• (c) judging whether or not a master file that corresponds to said type information exists in a master file storage device;
• and
• (d) combining said specific file with said master file and adding identification information, for identifying said specific file, identified from said additional information to said master file as reference information for referencing said specific file in said master file, if it is judged that a master file that corresponds to said type information exists.
