*NEW FLASH CHIP HAS KILLED SPIFFS

It seems the Chinese generic esp-01 board makers have switched to chip manufacturer PUYA as the supplier of their flash chips. I have bought from 3 different suppliers and they are all using the PUYA chip now.

I now have 75 esp-01 boards that I can't use.

Module: Generic ESP8266 Module
Flash Size: 1MB (64k SPIFFS)
CPU Frequency: 80Mhz
Flash Mode: QIO
Flash Frequency: 40Mhz
Upload Using: SERIAL
Reset Method: ck

Any sketch you try will fail to write to SPIFFS if you have a new module with the PUYA flash chip on it.

The only thing "Arduino" I've found that can write to SPIFFS is the "Upload Sketch Data" plug in. A sketch can then read the uploaded files, but it will fail to write any data to SPIFFS.

This is a link to the new flash chip from PUYA.

Unless your supplier still has some has old stock then the chances are that any new esp-01 module out of China will not support SPIFFS. I imagine that many other modules will also start using these flash chips so this is quickly going to become a major issue for a lot of people.
