Handbook Chapter 18 should include a section describing using exFat filesystems, and FAT32 filesystems. exfat requires using fuse-exfat port and using mount.exfat command.
I placed a request upstream to get a man page for mount.exfat. https://github.com/relan/exfat/issues/168
Maybe mention: mount.exfat-fuse
(In reply to Steven Friedrich from comment #0) Suggestion: rename current 18.8 (Using NTFS Disks) to "using Microsoft™ disk formats" or some such and add to it (with https://github.com/relan/exfat/blob/v1.3.0/fuse/mount.exfat-fuse.8 or the then-latest version as a reference), unless the procedure differs in more than the file system type name, which I doubt. Unfortunately, https://github.com/search?p=2&q=fat32+fuse&type=Repositories doesn't return anything promising for FAT32. No request in https://wiki.freebsd.org/WantedPorts that I can see, and I couldn't figure out how to search Bitbucket for project names before running out of attention span. (Does anyone know, or are there other public repo-hosting services I could search?)
(In reply to PauAmma from comment #3) Making a note that someone told me privately FAT32 is in-tree in msdosfs.
