Windows can now create 2TB FAT32 file systems

Even though FAT32 supports disk sizes of up to 2TB, and even though Windows can read FAT32 file systems of up to 2TB, Windows can’t actually create them. The maximum file system limit Windows can create with FAT32 is 32GB, a limitation that dates back to Windows 95 which has never been changed. It seems Microsoft is finally changing this with the latest Insider Preview build of Windows 11, as the format command can now finally create FAT32 file systems of up to 2TB.

When formatting disks from the command line using the format command, we’ve increased the FAT32 size limit from 32GB to 2TB.

Sadly, this only works through the format command; it’s not yet reflected in the graphical user interface, which is just so typically Microsoft. Of course, most of us will be using exFAT at this point for tasks that require an interoperable file system, but not every device accepts exFAT properly, and even those that do sometimes have issues with exFAT that are not present when using FAT32.

A more interesting new addition in this preview build is the Windows Sandbox Client Preview.

This build includes the new Windows Sandbox Client Preview that is now updated via the Microsoft Store. As part of this preview, we’re introducing runtime clipboard redirection, audio/video input control, and the ability to share folders with the host at runtime. You can access these via the new “…” icon at the upper right on the app.  Additionally, this preview includes a super early version of command line support (commands may change over time). You can use ‘wsb.exe –help’ command for more information.

Windows Sandbox is a pretty cool feature that provides a lightweight desktop environment in which you can run applications entirely sandboxed, separate from your actual Windows installation. Changes and files made in the sandbox do not persist, unless the sandbox is shut down from within the sandbox itself. There’s a whole variety of uses this could be good for, and having it integrated into Windows is awesome.

Windows Sandbox is available in Windows Pro or Enterprise – not Home – and is quite easy to use. Open up its window, copy/paste an executable to the sandbox, and run it inside the sandbox. As said, after closing the sandbox, all your changes will be lost. That process is still a bit clunky, but with a bit more work it should be possible for Microsoft to smooth this out, and, say, add an option in the right-click menu to just launch any executable in the sandbox that way.
