EXP-FILE:Express Logic FileX file system

FileX® (ST EXP-FILE) is Express Logic's high-performance MS-DOS compatible file system. It is fully integrated with ThreadX® and is available for STMicroelectronics' STM32 ARM® Cortex®-M based 32-bit microcontrollers. Like ThreadX®, FileX® is designed to have a small footprint and high-performance, making it ideal for today's deeply embedded applications that require file operations.

FileX® optimizes all file access in embedded environments. This is accomplished with an internal logical sector cache that FileX® automatically configures based on how much memory the application specifies when the media is opened. In addition to FileX®'s logical sector cache, FileX® also provides optimized file seek processing and the ability to pre-allocate contiguous clusters for files.
