File systems rarely get attention, yet they play a critical role in how reliably and efficiently data is stored. On Windows, NTFS has remained the default for decades, while the Linux ecosystem has steadily moved forward with newer designs such as Btrfs and ZFS. Microsoft, to its credit, has not stood completely still. It introduced ReFS, the Resilient File System, as a more modern alternative focused on data integrity. The problem is not what ReFS can do, but how little it is actually supported on consumer versions of Windows.
