ESP data upload tool did not appear

[fleure63]

I followed the tutorial to the letter but could not get the ESP8266 data upload tool to appear on the tool menu. SPIFFS has been depreciated and no longer works. After hours of trying different things, I finally uninstalled the Arduino ide, reinstalled an older version of the Arduino ide (1.8.9), initially this worked, then the data upload tool disappeared or couldn't find esptool.
So I installed an older version of the esp8266 community (2.5.0)
Located and deleted the Arduino 15 folder and started with an unused version of the code.
In the end it worked. So I'm just adding this comment so others working on this project don't waste so much time.

Running win 10....

Absolute Legend on this pickup, cheers for pointing it out as I was going insane until I saw this.
For anyone wondering if you go to Tools > Board > Board Manager > 8266 > 2.5.0
If like me and you just installed the latest version not thinking you will be greeted by the ability to re-upload your code and everything work fine.
