Microsoft has increased the maximum size limit for FAT32 partitions in the latest Windows 11 beta release, allowing users to format drives up to 2 TB in size. This is a significant upgrade from the previous 32 GB limit, which had been in place for years. The change will benefit users who need larger FAT32 partitions for legacy hardware, BIOS updates, or other specialized use cases.

Why it matters

The FAT32 file system has long been a standard for compatibility with older hardware and software, but its 32 GB partition size limit has become increasingly restrictive as drive capacities have grown. This update from Microsoft will provide more flexibility for users who rely on FAT32, allowing them to take advantage of larger storage volumes without having to resort to third-party tools.

The details

The new 2 TB FAT32 partition limit is included in the latest Windows 11 Beta Channel build, 26220.8165. Microsoft notes that this change is being made via a command-line update, rather than through the graphical disk management tools. While FAT32 still has a 4 GB file size limit, the increased partition size will benefit users who need to format large USB drives or create partitions for legacy hardware compatibility.

• The 2 TB FAT32 partition limit was first introduced in a Windows 11 Canary Channel build nearly two years ago.
• The change is now being rolled out to the Beta Channel, indicating it will likely be included in a future public release of Windows 11.

What’s next

As this is a beta feature, the next step will be for Microsoft to incorporate the 2 TB FAT32 partition limit into a public release of Windows 11, making it available to all users.
