I installed per instructions the ESP8266FS tool and I can see it in the 'tools' folder but it does not show up under the tools menu in the IDE as a choice? Tried re-installing several times but no difference. It worked OK on my old computer system.
I am working on a program by RUI SANTOS for using the ESP8266 SPIFFS function to download html and css data into the ESP8266 unit in SPIFFS.
I have further clarified my statements in my post. It should be installed into the Arduino "tools" folder and when the "tools" menu choice is clicked, there is supposed to be a choice for "ESP8266 sketch data upload". This tool should download a html and a css file into the ESP8266 SPIFFS memory instead of using an SD card to display the data in a browser.
I have done that. I removed the .jar extension and get the same result. The file is in the right place but does not shoe up in the tools menu as a function to act on. Cannot load "data" files into SPIFFS?
