Announcing EdgeFS 3.0 

We are pleased to announce the general availability of EdgeFS 3.0, a major release of our embedded POSIX-like file system for resource-constrained devices. This release expands EdgeFS’s POSIX compatibility, brings the userspace driver to Windows, and gives integrators more flexibility at format time. 

Highlights of the release 

• POSIX ownership and permissions — user and group IDs and the full set of mode bits, with access control enforced by the file system. This gives multi-application devices a native, file system-level foundation for isolating data between processes and user contexts. 
• Fuller POSIX compatibility — symbolic links, deleting open files, and an expanded POSIX-like API (openat-style relative-path operations, pread/pwrite, stat, and more) that makes porting existing code easier. Applications prototyped on standard Linux hosts move to EdgeFS with fewer changes. 
• Userspace driver now on Windows — the same FUSE-based driver now runs on both Linux and Windows, via Dokany. Development, integration, and diagnostic workflows can operate from either host operating system without maintaining separate tooling chains. 
• Flexible inode counts at format time — set the count explicitly, or let the formatter choose one automatically for variably-sized volumes. This makes EdgeFS easier to provision across a range of storage sizes and device configurations, from fixed embedded partitions to variable deployments. 

Built for the demands of modern embedded systems 

EdgeFS 3.0 continues Tuxera’s investment in a file system engineered for the realities of mission-critical devices — where security, portability, and provisioning flexibility matter as much as footprint and reliability. Devices in automotive, industrial automation, smart energy, and defense are increasingly running multiple applications on shared storage under strict traceability and data-isolation expectations. As edge devices take on new roles, including Physical AI workloads that sense, decide, and act in the real world, the underlying storage layer becomes a foundational element of system trustworthiness.
