Microsoft has announced an important update for Windows 11 that removes the long-standing 32GB size limit for FAT32 partitions when using the command line. This change, revealed in a blog post on Thursday, is part of the latest Windows 11 Canary build.
A Long-Standing Restriction
For nearly 30 years, Windows users have been limited to creating FAT32 partitions of only up to 32GB, even though FAT32 can technically handle volumes up to 2TB. This restriction dates back to the Windows 95 era, when former Windows developer Dave Plummer set the limit. In a recent post, Plummer acknowledged that the 32GB cap was a hasty decision made during development, which has persisted across several Windows versions.
Command Line Enhancement
The new update allows users to format FAT32 partitions as large as 2TB using the `format` command in the command line. However, this change currently applies only to the command line interface. The graphical format dialog box in Windows will continue to enforce the 32GB limit until Microsoft decides to update this aspect of the user interface. Previously, users who needed larger FAT32 partitions had to use third-party tools or special command-line techniques. With this update, Windows 11 users will be able to create these larger partitions directly from the command line without additional software or admin privileges.
Limitations and Alternatives
While removing the 32GB partition limit is a significant improvement, FAT32 still has limitations, including a 4GB maximum file size. Despite its age, FAT32 is still used in older devices that require it for USB drives or SD cards. More modern file systems, such as exFAT, offer better performance and features, but FAT32 remains relevant for certain applications.
New Features in the Canary Build
The latest Canary build also brings several new features, including an updated Windows Sandbox Client available through the Microsoft Store. This preview version introduces folder sharing, command-line support, and runtime clipboard redirection. Users can now share folders with the host system and manage audio and video inputs within the sandbox environment.
Additionally, Microsoft has made improvements to battery life for devices running this build, addressing a bug that caused the battery icon on the lock screen to show incorrect levels. The build also includes background network tests for devices in the Insider program, which will collect diagnostic data to help enhance network performance in future updates.
This update represents a major step in modernizing the Windows 11 experience, especially for users who rely on FAT32. While the removal of the 32GB limit in the command line is a welcome change, many are eager for a similar update to the graphical formatting tool. As Microsoft continues to evolve its operating system, users can anticipate more enhancements and new features in upcoming releases.
