PORTABLE SOFTWARE BASED ON SINGLE EXECUTABLE FILE USING APPLICATION FILE SYSTEM AND OPERATING METHOD THEREOF

摘要

PURPOSE: A portable software based on a single executable file using an application file system and an operating method thereof are provided to supply a customized mobile working environment to users by storing mobile software to mobile storage devices. CONSTITUTION: When a mobile software is executed, an execution engine unit(110) extracts an execution engine. A virtual library unit(120) stores a virtual execution library extracted by the execution engine. An image information unit(140) stores an execution file extracted by the execution engine. The execution engine creates an application process by combining the virtual execution library with the execution file. According to user level hooking, the virtual execution library controls the process path of a system function called from the application process.
