How to store data in ESP8266 and ESP32 flash memory

In this video I would like to present several ways how to permanently store data on your microcontroller. I'll show you work with memory from the simplest way (writing using EEPROM library), writing to NVS on ESP32 to simple operations (create, append, read, remove file) in the SPIFFS file system on ESP8266 and ESP32 (the size of the memory is determined by the version of the board you own. In video you can see some of boards including the amount of usable memory)

Thanks! I'm going to try the Preferences method, that is exactly what I was looking for!

I want to save the raw array into non-volatile memory. Can I save the
IRremtoe raw array by spiffs ? Which one is the best NVS, SPIFFS, EEPROM
? Thank you

ESP8266 and ESP32 don't have EEPROM so its not possible to save bew data there...

Thanks for the tutorial! Do you know if those Lolin32 boards support deep sleep? I've been searching but I couldn't find anyone who has made a project with them.

I need to save my data on esp using SPIFFS. But whenever I include SPIFFS.h library I have an error popping up as "SPIFFS.h no such file or directory". I have downloaded many files and libraries, still no use. kindly help me. Thank you.
