From Tuguu Software:
DownQuick takes advantage of the user's full bandwidth, linking to multiple connections with the hosting-server; this is how DownQuick is able to accelerate the download process. This feature can be fully customized by the user allowing them to select at all times the number of connections they wish to have, as well as deciding whether to use the full bandwith or not.
With DownQuick you can create a list with all of your desired downloads and even choose the order in which you want these downloads to be completed. If your internet connection drops, there is no need to worry since DownQuick will automatically continue with the download as soon as the connection is back online.
If the user requires the use of their full bandwith, this is no issue at all since Downquick can pause and resume all of your downloads. Queued downloads can be paused and resumed as many times as the user wants and they will never be lost; the download will always continue from where it was paused.
DownQuick can be set to manage all of your pending downloads in your clip-board. When you copy a URL to start a download, this will automatically be copied to your DownQuick list which will allow you to decide when you want to activate it.
We've developed DownQuick in a way that it uses the least possible amount of CPU, so you can leave the program running in the background without any problems at all.
