ReactOS adds NTFS installation support, drops FAT32 requirement
The open source ReactOS project announced it can now be installed directly onto NTFS-formatted partitions, ending its previous dependence on FAT32 drives. The new NTFS driver still lacks caching, journaling and security support, and the team has warned of possible undiscovered bugs.
GoKawiil's interpretation of the reporting above, not reported fact.
NTFS support removes a longstanding technical barrier toward ReactOS's goal of binary compatibility with Windows Server 2003, since NTFS has been the standard Windows filesystem since XP. The project's own caveats about missing caching, journaling and security features suggest this is an early-stage implementation rather than a production-ready one, meaning broader usability may still be some way off.
- ReactOS can now install directly to NTFS partitions, removing the FAT32 requirement.
- The new NTFS driver lacks caching, journaling, and security support, limiting performance and reliability.
- The milestone moves ReactOS closer to its goal of Windows Server 2003 binary compatibility, though beta status remains distant.
