I'm working with Arduino and an ESP32 board. I need to write some files in my ESP32.
but the problem is, SPIFFS doesn't work anymore. I don't know why... It worked till the day before yesterday.

But now when I use SPIFFS_Test from Arduino-Examples or this code:

#include "SPIFFS.h"





void setup() {



  Serial.begin(115200);



  if (!SPIFFS.begin(true)) {

    Serial.println("An Error has occurred while mounting SPIFFS");

    return;

  }



  File file = SPIFFS.open("/test.txt", FILE_WRITE);



  if (!file) {

    Serial.println("There was an error opening the file for writing");

    return;

  }



  if (file.print("TEST")) {

    Serial.println("File was written");

  } else {

    Serial.println("File write failed");

  }



  file.close();



  Serial.println(SPIFFS.exists("/test.txt"));

  Serial.println(SPIFFS.exists("/nonexisting.txt"));



}



void loop() {}

I just get the "FAILED ERROR."
What could be the reason?

I checked the directory and found some files that I created before.
I deleted them and it works again!
