Hi Sara, Ref: Module 13 unit 3 ESP32 filesystem uploader. Able to unpack the plugin file in (sketch dir) Arduino/tools/esp32fs1.1/ESP32FS/tool/esp32fs.jar Next instruction on IDE 1.8.5 select the drop down menu tools and then select ESP32 Sketch Data Upload. Learn with ESP32 book shows using IDE 1.8.5 tools menu. IDE 2.0.4 does not have this selection under tools drop down. What might be the alternative?
