exFAT is a file system that was released long after Windows 98 was discontinued. Those drivers will not help you there.

There has been some discussion of this over at the MSFN forums.

the very first introduction of exfat had built in backwards compatibility with fat32 systems. However you couldn't write a file over 4tb in dos windows nor use disk and defrag utilities on exfat partitions. That patch on xp was replaced and there were patches for vista+ the original has since disappeared.
There are a few places left in the world to get it last seen 2018 I may try fetch it and confirm.

here is a site with patches but they may be replaces with the security update shit that stopped fat32 accessibility http://greyghost.mooo.com/windows-exfat/

Oh, wow. I had no idea XP files likes this became a rarity! 😳

I downloaded many of these years ago from the MS page.
Still have them backed up..

Hi again!

I'm not sure if this is helpful, but there's an experimental exFAT driver for MS-DOS.
It's read-only and in an early stage, but it might be useful for file transfer (pendrive -> Win98 system / DOS 7.1).

"Currently it is read-only, and has some limitations (e.g., it uses codepage
866 permanently and doesn't use uppercase tables of exFAT - "thinks" that
Abc and abc are different filenames), bugs are possible to, because
testing was rather limited (but I've tested it under HX DOS extender under
plain DOS)."

"compiles with MSVC
detects multiple partitions, including exetnded ones
works with drives with sectorsize up to 4096"
