Can an interrupted download resume where it stopped?

Yes. FoxDL writes each piece straight into its final position and remembers the committed offset, so a dropped connection, a lost network or a force quit resumes from that byte rather than restarting from zero — as long as the server supports range requests.

The engine downloads a file in parallel chunks and commits each one as it lands. What is on disk is therefore always a valid prefix of the file, and the resume point is a fact rather than a guess.

Two things can still force a restart, and neither is under the app’s control: a server that refuses range requests (it answers 200 where it should answer 206), and an expired link — many hosts issue URLs that are valid for a few minutes only. In the second case, fetch the link again and start over.

Pull the Downloads list down to refresh it, then tap an item to resume it by hand.
