Now that we have the total content size of the file, we can check whether our file is partially downloaded. If so, we'll resume the download from the last byte recorded on disk:. What happens here is that we've configured the URLConnection to request the file bytes in a specific range.

The range will start from the last downloaded byte and will end at the byte corresponding to the size of the remote file. Another common way to use the Range header is for downloading a file in chunks by setting different byte ranges. For example, to download 2 KB file, we can use the range 0 — and — Another subtle difference from the code at section 2.
