If a file is bigger than 1024, do I take it that you split it between files?

E.g: 2kb is split 1024 file 1 and then 976 bytes for file 2?

No needs ... Take this new snippet instead :

Code: Select all    File f = SPIFFS.open("/Config.cfg", "r");
    if (!f) {
      client.println("Can't open Config.cfg !\r\n");         
    }
    else {
      char buf[1024];
      int siz = f.size();
      while(siz > 0) {
        size_t len = std::min((int)(sizeof(buf) - 1), siz);
        f.read((uint8_t *)buf, len);
        buf[len] = 0;
        client.println(buf);
        siz -= sizeof(buf) - 1;
      }
      f.close();


But beware that there is still the bug of SPIFFS where files bigger than 4096 is corrupting the filesystem parsing.
I will verify in few minutes if latest commits fix that ...

EDIT : The 4096 bug is still there...

You are pure genius

Loving this SPIFFS structure, amazing to have the ability to store files in flash on the fly.

Huge thanks buddy
