Where did you this file ID, and are you trying to troubleshoot a specific download error?
If you downloaded this file recently and can't find it, you can usually press (Windows) or Cmd + Shift + J (Mac) in your browser to see your recent download history and the file's exact location.
By default, most systems toss new files into a dedicated Downloads folder. Windows: You'll find it in File Explorer under "This PC".
When you click a download link, your browser "asks" the remote server for the data. The server sends it back in small packets that your computer reassembles.
