Also note from same Wikipedia entry:

Windows 2000 and Windows XP can read and write to FAT32 filesystems of 
any size, but the format program on these platforms can only create 
FAT32 filesystems up to 32 GiB. Third party utilities are available 
which can format larger FAT32 filesystems. Thompson and Thompson (2003) 
write[8] that “Bizarrely, Microsoft states that this behavior is by 
design.” A Microsoft knowledge base article[4] indeed confirms the 
limitation and the "by design" statement, but gives no rationale or 
explanation. However, a Microsoft TechNet article states that the 32 GiB 
limit was an arbitrary limit imposed because many tasks on a very large 
FAT32 filesystem become slow and inefficient.[9] Peter Norton's 
opinion[10] is that “Microsoft has intentionally crippled the FAT32 file 
system.”
