Microsoft boosts Windows’ FAT32’s partition size limit after nearly three decades
Microsoft righted an age-old “wrong” (at least for those who geek out on disk formatting) earlier this week. With its latest Windows 11 Insider Canary Preview Build (via The Verge), the company increased the maximum FAT32 partition size limit from 32GB to 2TB when using the command line. The boost from the previous limit, which its creator thought would be limited to the lifespan of Windows NT 4.0, comes after 28 years. FAT32 isn’t widely used today. Even SD cards, the last holdout, have mostly moved to exFAT. (FAT32 has other limitations for the modern world, like a 4GB file size limit.) So, the move appears to be more about making amends — a Windows geek’s equivalent of pardoning a historical figure who’s been dead for a century — than a practical change that will affect people today. The fact that the Windows GUI partitioning tool still includes the 32GB partition cap further decreases the odds that many will find much tangible benefit from the move. In a 2021 video on his “Dave’s Garage” YouTube channel, retired Microsoft system engineer Dave Plummer explained why he chose the 32GB partition cap. When he picked the limit “on a rainy Tuesday morning” in the mid-90s, he thought it would have an extremely short lifespan and would see an increase in the next revision. “I picked the number 32GB as the limit and went on with my day,” he said. “I didn’t start to regret that choice until SD cards got to the magic 32GB size many years later.” Plummer went on to dispute the myth that Microsoft imposed the 32GB cap to push the adoption of the company’s NTFS format. He explained that NTFS was already widely adopted and that, to his knowledge, Microsoft never promoted it or made a dime from licensing it. Instead, he says FAT32’s artificial cap was more about preventing wasted space (especially with small files) than deploying any sinister corporate strategies. If you really want to nerd out on ‘90s disk formats, Plummer’s three-year-old video goes into more detail about his arbitrary decision that — unbeknownst to him at the time — would last nearly 30 years.
