title: How to determing if a file has finished downloading in python
body: <p>I have a folder called <code>raw_files</code>. Very large files (~100GB files) from several sources will be uploaded to this folder. </p>
  
  <p>I need to get file information from videos that have finished uploading to the folder. What is the best way to determine if a file is currently being downloaded to the folder (pass) or if the video has finished download (run script)? Thank you.</p>
