Windows 10 only allows formatting exFAT and NTFS on non-removeable volumes sized larger than 32 GB with the default user interface, and FAT32 format is suggested for smaller volumes; command-line utilities don't accept quick format using FAT32 if volume is larger than 32 GB.
File Allocation Table (FAT) is a file system developed for personal computers and was the default filesystem for the MS-DOS and Windows 9x operating systems. [citation needed] Originally developed in 1977 for use on floppy disks, it was adapted for use on hard disks and other devices.
The byte at offset 0x026 in this entry should never become 0x28 or 0x29 in order to avoid any misinterpretation with the EBPB format under non-FAT32 aware operating systems. Fortunately, under normal circumstances (sector size of 512 bytes), this cannot happen, as a FAT32 file system has at most 0xffffff6 = 268435446 clusters.
A basic data partition can be formatted with any file system, although most commonly BDPs are formatted with the NTFS, exFAT, or FAT32 file systems. To programmatically determine which file system a BDP contains, Microsoft specifies that one should inspect the BIOS Parameter Block that is contained in the BDP's Volume Boot Record .
For example, the FAT32 file system does not support files larger than 4 GiB−1 (with older applications even only 2 GiB−1); the variant FAT32+ does support larger files (up to 256 GiB−1), but (so far) is only supported in some versions of DR-DOS, [2] [3] so users of Microsoft Windows have to use NTFS or exFAT instead.
All of the Linux filesystem drivers support all three FAT types, namely FAT12, FAT16 and FAT32.Where they differ is in the provision of support for long filenames, beyond the 8.3 filename structure of the original FAT filesystem format, and in the provision of Unix file semantics that do not exist as standard in the FAT filesystem format such as file permissions.

exFAT: No No No Partial (only if the file fits into one contiguous block range) No No No Yes (Linux) FAT12: Partial (only inside of compressed volumes) [61] Partial (only inside of Stacker 3/4 and DriveSpace 3 compressed volumes [30]) No Partial (only inside of compressed volumes) [62] No No No Yes (Linux) FAT16 / FAT16B / FAT16X
So, unless Microsoft changes its mind and puts exFAT into the public domain or offers it under a GPL-compatible license, exFAT isn't the solution for a future compatible and platform-independent universal exchange format for media larger than 2 TB we are desperately looking for, as FAT12/FAT16/FAT32 was (and still is) for media smaller than 2 TB.
