  • Microsoft is working to change the Windows 11 file system to ReFS.
  • ReFS overcomes the limitations of NTFS and has corruption resiliency.
  • The new file system is a hidden feature that must be enabled manually.
  • It’s unclear when the feature will be introduced to Windows 11.

Windows 11 may soon switch from the New Technology File System (NTFS) to Resilient File System (ReFS) on new installations. In the latest preview of Windows 11 available through the Dev Channel, a Twitter user has discovered that it’s now possible to enable a hidden option (ID 42189933) to install a clean copy of Windows 11 using ReFS.

ReFS is a technology designed to meet storage needs and overcome limitations from today and tomorrow. The file system can handle large volumes, share storage pools with different systems, and has corruption resiliency.

Initially, the company created the file system to replace NTFS, but it was only available for the server version of Windows. However, it appears that ReFS will finally come to the desktop version of the operating system.

According to another Twitter user, the installation didn’t show any issues with the new file system as the default, and Windows 11 worked as expected.

It’s unclear when Microsoft plans to replace NTFS with ReFS, but seeing that Windows 11 can install and boot from a ReFS partition, it seems that the days of the legacy file system are numbered. In the latest preview of Windows 11, you can use these instructions to try the system with ReFS.
