Method for dynamically generating a file allocation table base upon files storage information on a CD-ROM for retrieving compressed files directly from the CD-ROM

Abstract

In a typical storage medium, such as a magnetic hard disk, there is a file allocation table (FAT) stored thereon which is referenced each time the medium is accessed. Many data processing mechanisms rely on the existence of this FAT for accessing the medium. However, some storage media, such as CD-ROM's, do not have FAT's stored thereon. In order to properly interface FAT reliant data processing mechanisms with storage media having no FAT, file storage information is first obtained from the storage medium. Then, using this file storage information, a FAT having a format compatible with the data processing mechanisms is generated. Information from the FAT is provided to the mechanisms and, using this FAT information, the mechanisms can access information on the storage medium. Thus, even though the storage medium has no FAT, it is still accessible by FAT reliant data processing mechanisms.
