The maximal possible size for a file on a FAT32 volume is 4 GB minus 1 byte, or 4,294,967,295 (2 32 − 1) bytes. This limit is a consequence of the 4-byte file length entry in the directory table and would also affect relatively huge FAT16 partitions enabled by a sufficient sector size.
Limits; Max volume size: FAT12: 32 MB (256 MB for 64 KB clusters) FAT16: 2 GB (4 GB for 64 KB clusters) FAT32: 2 TB (16 TB for 4 KB sectors) Max file size: 4,294,967,295 bytes (4 GB - 1) with FAT16B and FAT32 [1] Max no. of files: FAT12: 4,068 for 8 KB clusters FAT16: 65,460 for 32 KB clusters FAT32: 268,173,300 for 32 KB clusters: Max filename ...
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.

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. Current 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.
FAT32 addresses the limitations in FAT12 and FAT16, except for the file size limit of close to 4 GB, but it remains limited compared to NTFS. FAT12, FAT16 and FAT32 also have a limit of eight characters for the file name, and three characters for the extension (such as .exe). This is commonly referred to as the 8.3 filename limit.
CompactFlash cards for use in consumer devices are typically formatted as FAT12 (for media up to 16 MB), FAT16 (for media up to 2 GB, sometimes up to 4 GB) and FAT32 (for media larger than 2 GB). This lets the devices be read by personal computers but also suits the limited processing ability of some consumer devices such as cameras .
In order to guarantee interoperability, DCF specifies the file system for image and sound files to be used on formatted DCF media (like removable or non-removable memory) as FAT12, FAT16, FAT32, or exFAT. [2] Media with a capacity of more than 2 GB must be formatted using FAT32 or exFAT. [2]
