Abstract
A flash file system for use with flash cards and internetwork operating system software is provided. Absolute path names are stored in the name field of existing files on flash cards. When the system is initialized, a directory structure is created and stored in RAM by accessing the absolute path names stored in the name field of each file on the flash cards. Accessing a file on a flash card is then accomplished by traversing the directory structure in RAM, and going directly to the precise location of the file on the flash card, thereby minimizing the amount of information that must be retrieved from the flash cards and greatly increasing the speed of accesses. Additionally, cards designed for use with older, non-modular internetwork operating systems may still be used, as name fields for files in these flash cards may easily be used to store absolute path names.
