A hierarchical folder security system for mapping files into and out of alias directories and/or real directories depending on: 1) the directory of the specific file being accessed, 2) the program thread requesting access to a memory storage device (114), and 3) the type of access request being made (i.e. load, save, run, etc.). For write access requests (i.e. save, modify, paste, delete, cut, move, rename, etc.), security controller (180) determines if the requested folder access address (150a) is associated with the requesting program's folder address (168). If it is, the file is written at absolute address (156b) on disk platter (160) through real folder map (152). If requested address (150a) is not associated with program folder address (168), then an alias directory address is created and the file is written at alias address (156a) through alias folder address map (154).
