So I would need to read/write flash with flash examples or SDFlash examples?

PS: can flash memory be written with VSCODE>Platformio?

Access to T-Echo's 2 Mbytes QSPI flash memory is possible with FAT filesystem and USB Mass Storage method. See this example:

so the flash data is added just the uf2 files when starting the USB Mass Storage method ??

on the same folder and all?

1) the uif2 firmware binary is applicable when the device in Adafruit bootloader mode only 2) in application mode (Arduino) -it is possible to use the same 'Drag and Drop' method as well, read

    • Adafruit SPIflash examples and
    • Adafruit TinyUSB Arduino examples

sorry I got lost for a moment:

My The T-echo is running as "Adafruit bootloader mode" and I can upload like a "external mass flash disk" the .uf2 file and also through VSCODE+Platformio. This works fine.

But this is where I need to be specific: will I be able to add also a .json file into the flash of T-echo by copying it also to the "external mass flash disk" that "Adafruit bootloader mode" enables?

Play with msc_external_flash sketch (mentioned above) to answer your question by yourself. You may borrow T-Echo specific GPIOs and flash types from SoftRF source code: https://github.com/lyusupov/SoftRF/blob/master/software/firmware/source/SoftRF/src/platform/nRF52.cpp#L199-L233
