Deleting files in subfolders

[danielkucera]

Hi, I was struggling with deleting files in subfolders (a/b.txt). At the end I was able to make it work like this:

  root.openRoot(volume);

  while (root.readDir(&p) > 0) {
    Serial.printf("%s\n", p.name);

    if(!memcmp("a", p.name, 1)){
      Serial.printf("%s found\n", p.name);

      uint16_t index = root.curPosition() / 32 - 1;
      SdFile s;

      if (s.open(root, index, O_READ)) {
        Serial.printf("b.txt remove ret: %d\n", s.remove(&s, "b.txt"));
      }
    }
  }

Is there some better way?
