Abstract
A system and method for allowing modification of information recorded in a read-only storage, including CD-ROMs, ROMs, read-only network directories, read-only files, and WORM media and devices (after being written or burnt.) The method and system intercepts read and write requests targetted at the read-only storage and remaps them when appropriate to a modifiable storage area. The modifying information may appear to the user to supplement, alter, or delete information recorded in the read-only storage. Information is combined from the modifiable storage and the read-only storage and presented to the user such that the entire read-only storage information need not be copied into memory.
