FAT32 (standing for File Allocation Table 32-bit) is a file system standard which used to be used widely by hard drives
everywhere until the release of ntfs
. FAT32 is now more commonly used on flash drives, however, smaller media like MicroSD cards, still use the FAT file system to use all the space it can. FAT32 requires 1 Gigabyte of allocated free space to function properly. In other words, if you put a FAT32 file system on a 4gigabyte microSD card, you would only be able to use 3.
The main reason why FAT32 is used on flash drive
s rather than NTFS is because the original FAT
file system cannot store files above 4 gigabyte
s. NTFS uses quite a bit more space than FAT because of it's structure and therefore not practical to use on media that requires a lot of free space (flash drives, external hard drive
My flash drive uses the FAT32 file system.
