wherein the file management information is stored in the storage device memory and comprises detailed information regarding manipulation of the file including;

a first date value indicative of when the file was created in a first location of the storage device memory,

a second date value indicative of when the file was moved from the first location to a second location in the storage device memory without further modification to said file,

whether and when the file was edited,

whether and when the file was deleted.

2. The portable storage device of claim 1, wherein the file management system generates and modifies the file management information when the file is resident in the storage device memory.

3. The portable storage device of claim 1, wherein said modification of the file management information takes place in response to an edit operation in which a content of the file is changed.

4. The portable storage device of claim 1, wherein said modification of the file management information takes place in response to a delete operation in which the file is deleted from the storage device memory.

5. The portable storage device of claim 1, wherein the file management system is configured to detect that a file transferred from the storage device memory to an appliance has been modified by the appliance and to update the file management information associated with said modified file in response to transfer of said modified file by the appliance to the portable storage device for storage in the data storage memory.

6. The portable storage device of claim 1, wherein the file management system is configured to detect that a file transferred from the storage device memory to an appliance has been modified by the appliance and to update the file management information associated with said modified file in response to the appliance not transferring said modified file to the portable storage device for storage in the data storage memory.

7. The portable storage device of claim 1, wherein the processor executes the file management system to generate said indications of when the file was created, edited, moved and deleted responsive to file transfer operations with said appliance.

8. An apparatus comprising a portable storage device configured for communication with an appliance, the portable storage device comprising storage device memory and a file management system, the file management system configured to store, in the memory, file management information associated with a selected file stored in said memory that has been created, edited, moved, and deleted, to transmit the selected file from the memory to the appliance, to detect modification of the transmitted file by the appliance, and to update said file management information resident in the storage device memory to provide a first date value indicative of when the file was created, a second date value indicative of when the file was edited, a third date value indicative of when the file was moved, and a fourth date value indicative of when the file was deleted, in the memory of the portable storage device, of said modifications by the appliance without a corresponding transfer of said modified file to the portable storage device.

9. The apparatus of claim 8, wherein the selected file and the associated file management information are respectively characterized as a first file and first file management information, and wherein the file management system is further configured to store, in the memory, second file management information associated with a second file stored in said memory, to transmit the second file from the memory to the appliance, to detect modification of the transmitted second file by the appliance, and to update the second file management information to provide a record, in the memory of the portable storage device, of said modification by the appliance in response to a transfer of said second modified file to the portable storage device.

10. The apparatus of claim 8, wherein the modification by the appliance comprises a delete operation upon the selected file so that a location of the memory at which the selected file was disposed is available to store a new file, and wherein the updated file management information identifies when the selected file was deleted.

11. The apparatus of claim 8, wherein the portable storage device further comprises a processor and wherein the file management system comprises programming code executed by said processor.

12. The apparatus of claim 8, wherein the memory comprises magnetic storage media.

13. The apparatus of claim 8, wherein the file management information associated with the selected file comprises a name of the selected file and respective date values identifying respective days on which the file was created, edited, moved and deleted.

14. The apparatus of claim 8, in combination with the appliance.

15. The apparatus of claim 14, wherein the appliance comprises a selected one of a digital camera, a printer, a digital telephone, or a personal digital assistant (PDA).
