The DR-DOS/OpenDOS Enhancement Project

I forgot to mention another link and some details:

Description mentioned in the previous post:

it contains basic structures of exFAT, and made in two languages (Chinese original and English translation). My impressions about exFAT: it is rather simular to FAT32, the main differences
1) The structures in MBR are not compatible to FAT12/FAT16/FAT32
2) One copy of FAT
3) Cluster bitmap
4) Changed format of directory entries: built-in LFN mechanism, label, FAT and cluster bitmap are files, full UNICODE support

The main advantages are: files larger than 4Gb, increased maximal number of clusters, faster search of free clusters.

It is still rather simple file system and it may be possible to implement it in DOS.

Discussion about exFAT in Russian; contains some attempts to find out the structure of exFAT by reverse engineering
