MECHANISM OF MODIFICATION APPLICATION TO FILES CONSISTING OF MULTIPLE PARTS Russian patent published in 2009 - IPC G06F15/16 

FIELD: physics, computer technology.

SUBSTANCE: invention concerns system and method of modification application to files consisting of multiple parts. Method of implementing modification involves receiving request for access to a stream in file consisting of multiple parts, identification of modification list related to the stream upon receiving request, the list also included to file consisting of multiple parts, and implementation of listed modifications before implementing the request. If recoding is requested data are encoded, and if reading is requested data are decoded. Modification list depends on the order of required modifications and includes data structure with first stream including display for stream comparison to the name of modification list, second stream listing each stream modification, third stream for identification of information related to each listed modification.

EFFECT: possible automatic extraction of auxiliary objects, solution of problems arising therewith by a single addressing main object.
