The only embedded file system built to protect critical data in resource-constrained environments
Tuxera EdgeFS
Product overview
Most file systems in small, embedded environments are outdated implementations that aren’t designed to protect your data. Tuxera EdgeFS is different. Built from the ground up for 100% data integrity, EdgeFS keeps your data safe even after sudden power loss. Backed by 30+ years of file system experience, EdgeFS delivers unmatched reliability in a compact footprint. It’s fully customizable, putting developers in complete control of your data. Paired with Tuxera FlashFX Tera, it works on top of any NAND or NOR device.
Our Dynamic Transaction Point™ technology prevents data corruption during unexpected system crashes and power loss. Your system quickly recovers to a known good state. This keeps your operations running smoothly with your data intact. All of this means faster boot times.
Built for resource-constrained environments, EdgeFS operates efficiently with minimal RAM and storage requirements. Our compact, well-structured file system can be configured to fit your exact needs, using as little as 4 KB of RAM while never compromising reliability.
With only 7,036 effective lines of code, EdgeFS makes certification straightforward and cost-effective. We provide all necessary artifacts to support your certification process, from market requirements to code testing.
“Using the products allowed my team to focus on the features that set our meters apart from the competition, and their support team gave us almost instant response assistance when we needed it.”
Product variants
Choose the solution that fits your needs.
EdgeFS is the ideal choice when you need to manage and store mission-critical data without straining CPU and memory usage. It supports larger files and volumes than standard FAT file systems, and works with virtually any storage media, including SD cards, eMMC, NVRAM, hard drives, and NVMe.
EdgeFS CERT works best for safety-critical applications with the highest reliability requirements. It follows the strict coding standard MISRA C and includes comprehensive documentation. For project certification, a complete set of artifacts is available.
EdgeFS NAND is designed specifically for SPI NAND flash, with a built-in flash translation layer. It handles everything you need to make NAND flash work properly—from wear leveling to bad block management and error handling. EdgeFS NAND keeps your data safe without any extra batteries or capacitors, saving you storage space and money.

Yes, EdgeFS is available as fully documented and well-structured source code. This makes it easy to integrate with your systems and to customize according to your exact requirements.
EdgeFS includes additional features that aren’t available in the GPL version, along with professional technical support. Our commercial license also gives you more flexibility in how you distribute your products without GPL licensing restrictions.
EdgeFS is highly portable and works on virtually any RTOS environment. It has been implemented on FreeRTOS, QNX, ThreadX, and many others. Our standard C code can be compiled on multiple tool chains and platforms, making integration straightforward regardless of your environment.
EdgeFS NAND supports most common SPI NAND flash parts, including single, dual, or quad SPI NAND.
It might be! EdgeFS has a smaller footprint than many options on the market, and it doesn’t hurt to ask. Reach out to us at sales@tuxera.com and get in touch to get the conversation going.
Technical specifications
Never overwrites live data. Once data is written, it’s always in a determinate state.
Mounts quickly and consistently after unexpected shutdown/power loss.
Ported to many RTOSs including FreeRTOS, SafeRTOS, μC/OS, ARM mbed, MQX, INTEGRITY, and eMCOS.
Ideal for resource-constrained environments. Configurable to use as little as 4 KB of RAM and 11 KB of ROM.
Works with a broad array of storage media including: HDD, eMMC, SD/MMC, NVRAM, USB mass storage, and SATA (or PATA) disks.
Metadata never points to wrong user data.
Tuxera EdgeFS offers three options for file system configuration. Each one is thread-safe and completely power fail-safe, protecting your file system structure and user data if power gets interrupted. Flexible transaction point configuration is also available for each option. Key file system operations are deterministic, providing unprecedented predictability.
