Reverse Engineering the Microsoft exFAT File System The Extended FAT File System (exFAT) is a new and not yet widely used file system. It has been out for a few years and it will gain acceptance and momentum with the release of storage
The FAT structure contain linked lists of files in the file system. Any file or directory entry in a (sub)directory list contain a cluster number for the first chunk of the file/directory. This cluster number also has an associated entry in the FAT. At this entry in the FAT a single word value either points to the next cluster/chunk or it contain an End-of-file value. These are the valid values:

For smaller drives, files and better recovery tools go for FAT But why not go for both, which is the best option in my opinion. Set aside some FAT so that you can run recovery tools, especially scandisk, so that you have something usable when things go awry, instead of the awful Windows System Tools.
A file system can be thought of as an index or database containing the physical location of every piece of data on the hard drive or another storage device. The data is usually organized in folders called directories, which can contain other folders and files. Any place that a computer or other
File Allocation Table (FAT) is a file system developed by Microsoft for MS-DOS and is the primary file system for consumer versions of Microsoft Windows up to and including Windows Me. FAT as it applies to flexible/floppy and optical disc cartridges (FAT12 and FAT16 without long filename support)
FAT32 is an advanced version of FAT file system. It can be used on drives from 512 MB to 2TB in size. One of the most important features of FAT and FAT32 is that they offer compatibility with operating systems other than Windows 2000 also.

The exFAT File System Structure RTFiles-32 optionally supports the exFAT file system introduced by Microsoft in 2006 as a successor of the FAT -12/16/32 file systems. It is supported by Windows Vista since Service Pack 1, Windows 7, and all later Windows versions.
It is a widely popular file system, which was introduced after the FAT file system. It was developed in 1993 and was first used in the operating system Windows 3.1. It supports the data storage capacity up to 256TB. It is used in all the latest versions of Windows such as Vista, Windows 7, XP, 2000.
File Allocation Table (FAT) is a computer file system architecture and a family of industry-standard file systems utilizing it. The FAT file system is a continuing standard which borrows source code from the original, legacy file system and proves to be simple and robust. [3]
This application note describes the usage of file I/O functions using Microchip’s memory disk drive file system library. Microchip’s memory disk drive file system is: • Based on ISO/IEC 9293 specifications • Known as the FAT16 file system, used on earlier DOS operating systems by Microsoft ® Corporation • Also supports the FAT32 file system • Most popular file system with SD
However, FAT’s simplicity is also its weakness as a general purpose file system for high performance computing. For example, to append data to a file, the operating system must traverse the entire cluster chain. Seeking to random places within a file also requires many reads within the FAT. For the sake of comparison, unix filesystems use a tree-like structure, where a cluster (also called a

The File Allocation Table (FAT) file system was introduced with DOS v1.0 (and possibly CP/M). Supposedly written by Bill Gates, FAT is a very simple file system — nothing more than a singly-linked list of clusters in a gigantic table.

However, FAT’s simplicity is also its weakness as a general purpose file system for high performance computing. For example, to append data to a file, the operating system must traverse the entire cluster chain. Seeking to random places within a file also requires many reads within the FAT. For the sake of comparison, unix filesystems use a tree-like structure, where a cluster (also called a
