Method of enabling an application to access files stored on a removable storage medium

摘要

Symbian OS applications assume a directory structure that has been defined by Symbian and defines a standard set of directories starting from the root of a drive. This is not compatible with the Memory Stick standard. The method presented provides applications with a drive that appears to be a standard Symbian drive but actually transparently maps to a safe area on the Memory Stick. It is also possible to access special Memory Stick defined root directories (e.g. for pictures and audio) and to map these directories to standard Symbian-style directories.
