File system for IC CARD comprising an
integrated circuit IC, non volatile memories ROM and / or E2PROM and at least a
volatile memory RAM, for organizing files storage inside the non volatile memories and defining, through a logical structure, their
accessibility by an IC Card application, stored inside one of said non volatile memories or IC or loaded in the
volatile memory and in communication with an external read-write device; an interchange application, stored inside one of said non volatile memories, drives the organization of files in an additional tag-length logic structures of arbitrary length, allowing the identification of files through
alphanumeric identifiers of arbitrary length and extension, and their
accessibility by an external read-write device, eventually non IC card purpose, like a
workstation a
personal computer or a PDA interconnected to the IC Card by means of standard
communication interface. The
file system organizes said tag-length
logic structure as individually memory blocks, each identified by an hexadecimal identification number and a
block size and one of these memory blocks, more particularly one per
non volatile memory, describes the content of the
non volatile memory, comprising the number of files stored, their file name and extension and, for each file, the location of memory blocks composing its content.
