If you're a normie that's reading about this then you definitely don't have any creeping anxiety about data loss, the ever growing encroachment of disappearing backups and historic Internet media or any concept of nearline storage and possibly even the concept of what files ARE let alone how they exist in a volume. FAT16 and FAT32 were those old file systems that just barely got us through the Win9X - WinXP era and it wasn't until DVD backups became a hot idea that we collectively decided on using literally anything else.
Most computers of that time period didn't have 1GB of local storage and I especially remember fighting this because I had maybe half.
FAT16 was limited to 2GB in total volume size and served as boot media for DOS/Win95 environments.
File NAMES were limited to eight dot three letter:
FILENA~1.TXT and extremely limited in all functions.
FAT32 was similar, had no foreseeable limit to volume size, is compatible with everything but file sizes were limited to 4GB.
This means that install packages on a modern Win10 distribution (install.wim) would not be able to exist. It won't write to disk.
This also means that entire volume images 4GB and larger won't write either. Better jump to NTFS, ReFS or Ext3 or whatever else you used between the Win2000 era and today.
