<p>A computer device driver for accessing modified files (520) held in archives (516) in a memory device (10) by reading a modified file (520) from an archive (516) in the memory device (10) demodifying the file in RAM (10) and retaining the demodified file in RAM (10) in whole or in part so that operations to the memory device (10) can be performed on the demodified file by the operating system without having first to write the demodified file to the memory device (10). The device driver also accesses the file in said RAM (10) and changes the contents of the file; and returns the file to the archive (303) in said memory device (10).</p> |
