Extended File Allocation Table for flash link

RE: "Advantages"

"Free space allocation and delete performance improved due to introduction of a free space bitmap.'

From the free space bitmap link noted above:

"Free space bitmaps are one method used to track allocated sectors"

"The simplest form of free space bitmap is a bit array, i.e. a block of bits."

This deal still utilizes file allocation tables(FAT)

It is advanced by implementing bit mapping as well... note above, a whole array (or erase block) of memory is dedicated .

E.Digital does not bit map or allocate space in FAT manners.

There is overhead to the above, and it all grows as data grows.

e.Digital's OS file administration is written directly into the file segments as they are being created....no FAT or bit mapping.

With that, MOS can administer the file attributes of FAT file systems, or any system, without allocating space, or by additionally tracking the allocated space as the above does.
