Next, it doesn’t treat special files any differently and won’t create their clones.
The copyfile() method makes use of lower-level function copyfileobj() underneath. It takes file names as arguments, opens them and passes file handles to copyfileobj(). There is one optional third argument in this method which you can use to specify the buffer length. It’ll then open the file for reading in chunks of the specified buffer size. However, the default behavior is to read the entire file in one go.
