Solid File System™ (SolFS) - Embedded File System with encryption and compression

Introduction

If you need to use or create a powerful file system for your custom device, be it an MP3 player, camera, or just a flash memory controller, we have an offer that fits all your requirements. A file system that provides encryption, compression, journalling, symbolic links, streams and more. A file system, that is not based on FAT, and so is free of all it's limitations (and patents, of course). And all this functionality fits into 300 K of code.

SolFS is not just a specification or a proof-of-concept system. SolFS is already implemented on a number of platforms including Windows, .NET, Windows Mobile, PalmOS and Unix. Since it is written in ANSI C, SolFS offers very flexible code base for use with both big-endian and little-endian systems for which ANSI C compiler exists.

Possible uses

SolFS can be used in any device, that needs to store data in persistent storage (disk drive, flash memory etc). Specifically, the best features of SolFS can be used in

• DRM-enabled devices to provide device-dependent encryption of the data;
• Multimedia devices to organize information in database-like structure;
• Data collection devices and industrial appliances to store more data on the device;
• Flash memory to provide a file system with advanced features and save on development of custom storage formats

Main features

SolFS provides built-in compression functionality, which lets you increase capacity of the storage without adding a compression layer to your data management code.

With built-in symmetric encryption, based on modern industry standards, such as AES256 and SHA2, you can protect the data from theft or implement DRM features easily.

Journalling and embedded check-and-repair functions let you guarantee data integrity and fail-safety.

You can manage multiple independent volumes with SolFS. This lets you handle many storage media devices (for example, built-in storage and an external flash card) at the same time.

SolFS speed is comparable to speed of other advanced file systems on the market, such as NTFS (on Windows).

What we offer

We offer a cross-platform file system engine, which can be used on 16-bit, 32-bit or 64-bit platforms without major changes. The package consists of the source code, accompanying documentation and description of the file system format.

File system and block drivers for Windows NT/2000/XP/2003/Vista and Windows Mobile are available and can be licensed together with the Embedded Edition.

The license for embedded edition is royalty-free and includes one-year support and free upgrades.
