The exFAT format allows individual files larger than 4 GB, facilitating long continuous recording of HD video, which can exceed the 4 GB limit in less than an hour. Digital cameras using FAT32 will break the video files into multiple segments of approximately 2 or 4 GB. EFS supported in Windows 10 v1607 and Windows Server 2016 or later. [19]
[38] [39] The built-in Windows shell disk format tool on Windows NT arbitrarily only supports volume sizes up to 32 GB, [nb 4] but Windows supports reading and writing to preexisting larger FAT32 volumes, and these can be created with the command prompt, PowerShell or third-party tools, [41] or by formatting the volume on a non-Windows system ...
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.
A block, a contiguous number of bytes, is the minimum unit of storage that is read from and written to a disk by a disk driver.The earliest disk drives had fixed block sizes (e.g. the IBM 350 disk storage unit (of the late 1950s) block size was 100 six-bit characters) but starting with the 1301 [8] IBM marketed subsystems that featured variable block sizes: a particular track could have blocks ...
The total number of sectors (as noted in the boot record) can be larger than the number of sectors used by data (clusters × sectors per cluster), FATs (number of FATs × sectors per FAT), the root directory (n/a for FAT32), and hidden sectors including the boot sector: this would result in unused sectors at the end of the volume.
Therefore, most users (and device manufacturers) simply use FAT32 instead of exFAT also for media larger than 32 GB, whenever they have a choice. Another possible explanation for the user's observation are bugs in a specific exFAT implementation, which would not belong into the article as well, unless very prominent.

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.
