This tutorial explains how to get started with the FAT file system on the ESP32, running the Arduino core.

Important: The partitions changing procedure was needed at the time this video was recorded. Nonetheless, it's possible that in the future, the Arduino core is update to have other configuration that includes a partition for a FAT file system. If your default partition schema file already has a partition for the FAT file system, please ignore that part of the video.
