I am having issues reading a file back that I have uploaded using ESP8266FS.

Uploading the file, everything seems OK... (note: I am uploading a file called 'index.html')

Code: Select all[SPIFFS] data    : C:\Users\harol\OneDrive\Documents\Arduino\upload\data
[SPIFFS] size    : 2024

However, when I use the following sketch to see if the file opens...

Code: Select all#include "LittleFS.h"

void setup() {
  Serial.begin(115200);

  Serial.println(":mount_fs");
  Serial.print(F("mounting file system..."));
  if (LittleFS.begin()){
      Serial.print(F("done.\n"));
  } else{
      Serial.print(F("failed.\n"));
  }

  File file = LittleFS.open("./index.html", "r");
  if(!file){
    Serial.println("Failed to open file for reading");
    return;
  }

 
  Serial.println();
  Serial.println("File Content:");
  while(file.available()){
    Serial.write(file.read());
  }
  file.close();

}

void loop() {
  // put your main code here, to run repeatedly:

}


Console:

The serial monitor returns:

Any thoughts/suggestion would be gratefully received... I guess I have a configuration wrong somewhere.
