Windows 95 introduced long filenames to FAT, and implements the file system in the VFAT.VXD driver. “VFAT” is thus sometimes thus shorthand for FAT with “Windows style long filenames”. It can be applied to all variants of FAT, such as FAT16 and FAT32.

FAT32 is a variant of FAT introduced in the mid 90s with Windows 95 OSR2 that better supports large hard drives (beyond size limits, cluster sizes were getting too large on FAT16 drives etc.).
