Say, user wants to download a file of size 50MB. In the first session, user downloads first 10MB chunk. If the download needs to be resumed, at some point, download manager will ask for bytes following first 10MB which has already been downloaded. Since, the site does not allow multi-part sharing, it always starts serving bytes from the very beginning. Hence, resuming the download is impossible.

But In case of multipart downloading how this process of resuming download works?

Oh! BTW, have you ever thought how you download a file? It's the data bytes delivered over HTTP/FTP or other similar protocol.

I think it is delivered over HTTP as well as FTP. But I do not have a very good idea about how multipart download actually happens.

If the download for some reason gets broken, it will skip all the bytes that had been downloaded on the previous attempt and only write new ones after the part that already been written. It is used for downloading DVD files that take a long time to get.
Doesn't save you from re-downloading something from scratch but at least gets the job done.
If you're looking for a good download software, I'd recommend wx fast downloader. Really great to get things done.
Welcome to reboot.
