title: How to attach a file using email operator in Airflow
body: <p>I've used the argument files =["abc.txt"]. I got the info from the airflow docs...<a href="https://airflow.readthedocs.io/en/stable/_modules/airflow/operators/email_operator.html" rel="noreferrer">https://airflow.readthedocs.io/en/stable/_modules/airflow/operators/email_operator.html</a></p>
  
  <p>But I'm getting the error that the file is not found. My question is from where do this airflow will pick my file. Is it from GCS Bucket or DAG folder in the composer environment?</p>
  
  <p>Where I need to upload a file and what is the correct syntax for 'files' argument?</p>
  
  <p>Thanks in advance.</p>
