Yesterday, Microsoft unveiled a new preview version of Windows 11 for Windows Insiders, introducing a noteworthy enhancement: the maximum size limit for FAT32 partitions has been increased to 2TB.
Understanding FAT32’s Evolution
FAT32, a file system designed for data storage and management on drives, has a rich history. Originally developed as FAT (File Allocation Table) in 1977 for floppy disks, it underwent several iterations—FAT12, FAT16—before Microsoft rolled out FAT32 in 1996 to accommodate the growing demand for larger drive capacities. This means that FAT32 has been a staple in the tech world for nearly three decades.
For much of that time, Microsoft maintained a somewhat arbitrary 32GB capacity limit on FAT32 drives, despite the fact that the file system can technically support sizes up to 16TB. Interestingly, while Windows can read larger FAT32 drives formatted elsewhere, it has historically been unable to format drives in FAT32 beyond the 32GB threshold. This limitation seemed to align with Microsoft’s strategic push towards its own file system, NTFS, which was introduced in 1993 and became the default for Windows operating systems starting with Windows XP.
With the latest Windows update, currently accessible only to Insiders on the Canary channel, users can now format FAT32 drives up to 2TB. However, this functionality is currently limited to the command line’s format command; the familiar drive formatting dialog box still adheres to the previous 32GB cap.
File Size Limitations Remain
It’s important to note that while the maximum capacity for FAT32 drives has been raised to 2TB, the individual file size limit remains at 4GB. This constraint continues to be a consideration for users who manage large files.
The rationale behind the original 32GB limitation can be traced back to Microsoft’s promotion of NTFS, which offers enhanced features and capabilities suited for modern computing needs. Today, most Windows users have transitioned to NTFS, leaving FAT32 primarily for use on flash drives and SD cards that may interact with older devices.
Nonetheless, the ability to create larger FAT32 drives directly within Windows is a welcome development, eliminating the need for third-party software solutions.
