How FAT Systems Work
An index table of the files kept on the device or in the system is created by the FAT system. There is a record in the index table for every data cluster (data storage area). The next cluster number, an EOF (end of file) marker, any unused disk space, and other specifically designated drive regions are all contained in the entries.
Up until the file’s finish, the operating system (OS) searches for the cluster number of each subsequent section.
FAT Full Form
FAT stands for File Allocation Table. It is the name of the computer file system architecture family. The FAT file system has 8-bit FAT, FAT12, FAT16, FAT16B, FAT32, ExFAT, FATX and FAT+ variants. It is one of the best filesystems when it comes to being lightweight and compatible.
