Windows 10 Insider Preview Build 20211 supports WSL2 system ext4 file system

2 min read

Microsoft has now launched the developer beta this week, the version number is Windows 10 Insider Preview Build 20211, which mainly fixes some bugs and functional problems.

The default application search function that has been previously provided to some users is now available to all users, and users can experience it in the default application settings after upgrading.

This time, it is optimized for the WSL 2 function. Now you can directly access file systems that are not supported by Windows 10, such as ext4, through the subsystem.

For example, Windows 10 does not natively support the ext4 file system, but after the test update, WSL2 can be used to read and access these unsupported file systems.

If users use Windows and Linux dual systems and install them on different hard drives, they can now access Linux partitions in Windows WSL2.

For detailed descriptions of this function and common command lines, please visit the page.
