ESP8266 Sketch Data Upload

Trying to upload my "Index.html" file to ESP8266 12E board FLASH. Can't find IDE/tools tab; "ESP8266 Sketch Data Upload". Have installed esp8266fs.jar in local tools folder. This worked in previous IDE version.

Hi @marshman. Thanks for giving the Arduino IDE 2.x release candidate a try! Unfortunately, the IDE does not currently have support for these tools. That deficiency is being tracked by the Arduino IDE developers here:
