works good and has much potential
(Sorry for my poor english but this would be an important feedback) It does work just what it says, but it can be smarter. The app devides the file into some identical files and each thread downloads the segment. However, even if one thread have already finished, the app does not make another thread which other download accelerator makes. You have to wait until for each thread downloading all their segment evenif the threads have various download speeds.
