FAT32, released by Microsoft in 1977, is the most common version of FAT file system. Due to its powerful compatibility, FAT32 is widely used in many embedded and portable devices. But for some old devices, like XP computers, XBOX360 and PSP, they only support FAT32.

Sometimes in daily life, you may need to format your drive to FAT32, because the device only recognizes FAT32, rather than exFAT or NTFS. Usually, it is very easy to format it to FAT32 just with Windows File Explorer, Disk Management or Command Prompt.
