![]() ![]() FAT32 supports volume sizes up to 16 TB.FAT16 supports volume sizes up to 4 GB.FAT12 supports volume sizes up to 32 MB.Here are the volume sizes for each version: As FAT developed, the supported volume sizes increased. ![]() The main difference between the different FAT file system versions is the size of the volumes you can create. Main Differences Between FAT12, FAT16, and FAT32 FAT is thus, the most widespread file system architecture. Apple computers, using the MacOS X operating system, support it on volumes other that the boot disk. Movable storage devices, such as USB sticks, flash and solid state memory cards, and many more.īasically all operating systems consider it. It is still in use, being the default file system in many re Overall, the FAT file system architecture is simple, efficient and has passed the test of time. The FAT32 file system has maximum file size of 4G limitation, which is due to the length of the entry in the directory table. Sub-directories are treated in a similar manner. Using it, the operating system can build a cluster chain until it reaches the end-of-file marker. In the case of the root directory, the FAT table contains the number of the first cluster of each file in that directory. Reserved are special clusters used by the operating system.ĭirectories are described in the same table. ![]() Otherwise, it differentiates between unused and reserved clusters. For used clusters, each entry contains the number of the next cluster, or an end-of-file marker. The FAT table contains entries for each cluster. The FAT system divides the storage space into clusters. The main element of this file system is the File Allocation Table (FAT), which is allocated at formatting time. ![]() Usually, Microsoft doesn’t differentiate between the older versions, and refers to them as FAT. Originally, using 8 bits per entry, it has evolved into versions FAT12, FAT16 and FAT32, each using 12, 16 and 32 bits respectively. Microsoft promoted it through its DOS and Windows operating systems. This file system has been around since the 1980s. The FAT file system derives his name from its main component: the File Allocation Table. How do I recover data from a FAT file system ![]()
