Is exFAT 64 bit?
exFAT is a proprietary Microsoft file system that was designed to bridge the gap between the NTFS file system and the more dated FAT32 file system. Its main advantages are that it can store files over 4GB since it is a 64-bit file system.
How does FAT file system work?
How it works. The FAT file system is based on the FAT, a structure that maps the locations of the clusters in which files and folders are stored on the disk. The FAT records the location of each cluster that makes up a given file and the sequence in which it is stored.What is .FAT1 file?
The File Allocation Tables (FAT1 & FAT2) The FAT file system organises sectors (a sector is the smallest unit of a storage media, measures 512 bytes in HDDs) into clusters of a predefined size (cluster sizes typically range from 1 sector to 128 sectors which is 64 KiB).
What is FAT16 32?The FAT32 file system offered two main improvements over FAT16. First, FAT32, being a 32-bit file system, supports much larger disks than the FAT16 file system.

Why is exFAT bad?
It is not a journaling file system, so more chance of file system corruption than e.g. NTFS or ext4. It is not quite as widely-supported as FAT32. exFAT (and the other FATs, as well) lacks a journal, and so is vulnerable to corruption when the volume is not properly unmounted or ejected, or during unexpected shutdowns.

exFAT is a tradeoff between responsiveness for small files and write speed for large files (15mb/s). NTFS is very slow for numerous small files but the fastest for very large files (25mb/s).
What is cluster in FAT?
Possible values for FAT16 are: 0000: free, 0002-ffef: cluster in use; the value given is the number of the next cluster in the file, fff0-fff6: reserved, fff7: bad cluster, fff8-ffff: cluster in use, the last one in this file.
