UTFS is a lightweight, zero-allocation file system for embedded devices (opens in new tab)

CLI Systems has introduced UTFS (μTFS), a simple, lightweight embedded storage system designed for small MCUs. Unlike traditional file systems like FAT32 or EXT4, or even lighter options like LittleFS and SPIFFS used on boards like the ESP32, UTFS is much simpler. It does not use dynamic memory and avoids complex features like wear leveling, making it easier to use on low-resource devices. Designed for flat, byte-addressable memory like raw EEPROM, CPU flash pages, or external SPI/I²C flash, ...
