VS Code & PlatformIO - How to upload sketch data to the SPIFFS disk of ESP32

This post is about how to upload sketch data to the SPIFFS disk of ESP32 in VS Code using PlatformIO.

Below is the version info.

http://docs.platformio.org/en/latest/platforms/espressif32.html#uploading-files-to-file-system-spiffs

1. Make sure the "data" folder that contains the data / files to be uploaded to the SPIFFS disk is at the same level as the "src" folder.

2. Be sure to close the Serial Monitor terminal. If it's not closed, click the trash can button to close it.

3. Switch to the cmd terminal.

4. Issue the command "platformio run --target uploadfs" to start uploading sketch data to the SPIFFS disk.

Note, be sure to press and hold the IO0 button of the ESP32 module when seeing "Serial port COM7" and release it when seeing the next message - "Connecting........__".

The sketch data is now uploaded to the SPIFFS disk of the ESP32 module.

Note, if IO0 button is not pressed in time, error such as the one below will occur.
