zsync — Partial/differential file downloader. HTTPS is not supported - use HTTP URLs only. See also: `rsync`

Download a file using a `.zsync` control file

zsync {{path/to/url.zsync}}

Use a local file as a seed to avoid re-downloading unchanged parts

zsync -i {{path/to/existing_file}} {{path/to/url.zsync}}

Save the updated file under a specific name

zsync -i {{path/to/existing_file}} -o {{path/to/new_file}} {{path/to/url.zsync}}

Resume a partial download and keep the temporary file

zsync -k {{path/to/url.zsync}}

Run in quiet mode with minimal output (no progress bar, download rate, or ETA display)

zsync -q {{path/to/url.zsync}}
