What Is FAT32 & Why Format to It

What Is FAT32

When it comes to FAT32, you should know it refers to a version of the file allocation table (FAT) which is available since Windows 95 OSR 2 and Windows 98. It increases the number of bits used to address clusters and also reduces the size of each cluster. As a result, it can support larger disks (up to 2 terabytes) and better storage efficiency (less slack space).

FAT32 is an old file system, so many old operating systems including Win95, Win98, Win2000, Win2003, Win Vista and more support this file system.

What’s more, as for some old game consoles, FAT32 is available. When reading here, you know FAT32 has very good compatibility. Besides, USB drives adopt the FAT32 file system by default.

Why Format to FAT32

Generally speaking, this is mainly because of the better compatibility of FAT32, despite that it can not support files larger than 4GB file size for single files.

Let’s focus on a common issue for more information: What is the best format for a USB drive?

If you are using a USB drive but the partition is formatted to NTFS before, now you want to use your USB disk to connect to a game console PS3/PS4, Linux, or Mac OS X. In this case, you need to use a FAT32 formatter tool to format USB to FAT32. Otherwise, PS4 can’t read USB flash drive or you are unable to write in Mac OS/Linux.

Moreover, there is another case showing the necessity of formatting a hard drive to FAT32. You want to connect your USB disk or Seagate/Western Digital external hard drive to a NAS but the NTFS permissions cause the NAS not to access the drive. Under this circumstance, the better solution is to adopt FAT32.

Bottom Line

To format your USB flash drive, SD card, or external hard drive to FAT32, use one of the four formatters listed above. If your drive is over 32GB or contains data you want to keep, MiniTool Partition Wizard is recommended; otherwise, use a built-in Windows tool.

By contrast, we highly recommend that you use MiniTool Partition Wizard to convert NTFS to FAT32 or format SD card, USB disk, or external hard drive to FAT32 without any limit.
