(also FAT, FAT16)
File allocation table (also known as FAT) is a file system developed for hard drives by Microsoft. Operating systems use it to manage hard drive files. The FAT system uses a table to track the clusters on a storage volume and how those clusters link together through associated directories and files. The table plays a vital role in file storage and allocation. The acronym (FAT) refers to the file system but can sometimes refer to the table itself.
