Key Highlights
- Microsoft is removing the 32GB FAT32 formatting limit in new Windows 11 Insider builds.
- Users can now format drives up to 2TB using FAT32 via Command Prompt.
- The update is currently limited to preview builds and is not yet available to all users.
Microsoft has introduced a major Windows 11 update that removes the long-standing 32GB limit on formatting drives with the FAT32 file system.
The change is available in Windows 11 Insider preview versions, including Dev Build 26300.8170 and Beta Build 26220.8165. With this update, users can now format storage devices up to 2 TB in size using FAT32 from the Command Prompt.
Microsoft confirmed that the update increases the FAT32 formatting limit from 32GB to 2TB when using command-line tools.
A Decades-Old Limitation Finally Addressed
The 32GB cap has been part of Windows for decades, despite FAT32 itself supporting volumes much larger than 32 GB. The limitation was not technical but rather an internal design decision made during early Windows development.
According to Dave Plummer, a former Microsoft engineer, the restriction dates back to 1994 during the development of Windows NT. At the time, the limit was introduced as part of formatting tool design rather than due to file system constraints.
As a result, users who needed to format larger drives in FAT32 previously had to rely on third-party tools or alternative methods such as PowerShell commands.
Command-Line Access Only for Now
The update currently applies only when formatting drives in the Command Prompt (also known as Terminal). The Windows graphical interface still enforces the 32GB limit for FAT32-formatted drives.
Additionally, while the volume size limit has been expanded, the 4GB maximum file size limit of FAT32 remains unchanged.
This means that although users can now format larger drives, individual files stored on FAT32 volumes will still be restricted to 4GB.
What This Means for Users
While modern Windows systems primarily use NTFS, FAT32 remains widely used for external storage devices due to its compatibility across different platforms.
With the removal of the 32GB cap, users can format larger external drives in FAT32 without third-party tools, making it easier to maintain compatibility with older systems and devices.
However, the feature is currently limited to Windows Insider preview builds. The traditional 32GB limit still applies to standard versions of Windows 11 and will only be lifted for all users once the update is officially rolled out.
Additional Improvements in Insider Builds
Alongside the FAT32 update, Microsoft has also introduced performance improvements in storage settings within these Insider builds.
The company stated that users can expect faster operations when managing storage, although full details of all changes are outlined in the Insider release notes.
