vFAT - Virtual File Allocation Table

VFAT (Virtual File Allocation Table) is a FAT file system extension introduced with Windows 95, which allows long file names relaxing the 8.3 file name convention followed by the original File Allocation Table (FAT). The FAT file system limits file names to the 8.3 naming convention, which allows a maximum of eight characters before the period and no more than three characters after the period. It also imposes certain other rules for naming a file such as file name must begin with a letter or a number; it cannot contain white spaces, etc.

Long File Names in vFAT

To use long filenames (LFN) in addition to classic 8.3 filenames (SFN), an optional program extension is introduced along with the existing FAT file system structure. This transparent method of allowing long filenames in the FAT file system without changing its directory structure, is known as VFAT or Virtual File Allocation Table. This extension is referred to as a driver, as the users with operating systems other than Windows 95 have to install and use it in order to access the FAT partitions written by Windows 95. The VFAT extension uses 32-bit code, runs in protected mode and makes use of VCACHE for disk cache.
