But you'd need to be sure that none of those files are greater than 4 GB. For example, if you need to boot up an old computer, maybe with a different operating system, and backup some of its files.

These days, the only reason why you'd choose to format a drive to FAT32 is for compatibility. Also, it's a little more difficult to format a drive larger than 32 GB to FAT32 on Windows 10. On the other hand, FAT32's max file size of 4 GB is almost nothing now that phones can record 4K videos. (But it would be nice to have a 128 PB USB drive, wouldn't it?) Note that the maximum drive and file size of NTFS and ExFAT is so large that there's basically no limit. ** 1 exabyte is about 1 million terabytes * 1 petabyte is about 1 thousand terabytes However, though FAT32 is well supported, its maximum drive and file size is severely limited when compared to newer formats like NTFS and ExFAT: Meanwhile, macOS can only read NTFS drives, and you would need to install third-party software to write back to the drive. Every major operating system will allow you to read and write from a USB flash drive that's formatted to FAT32.

Of those three common formats, FAT32 is the oldest and most widely supported. Some of the most common file system formats for portable storage devices are FAT32, NTFS, and ExFAT. What's a file system?Ī file system is a standardized way of organizing data on a computer storage device like a flash drive or HDD.Ī file system divides a storage device into virtual compartments, almost like a wall of post office boxes, and keeps track of all the information that gets stored in each box. In this article we'll go over what a file system is, the FAT32 standard, and several ways to format a storage device to FAT32 on Windows 10. If you need to format a USB flash drive, HDD, SDD, or some other form of storage to FAT32, you've come to the right place.
