Well I now use a great tool called Free Download Manager (FDM) infacxt I have been using it for about 2 years.
This is a full-featured download accelerator and manager. It is absolutely free! Using this software product you can easily download a list of files and whole web sites from any remote server via HTTP, HTTPS and FTP. With FDM the downloading process will be as easy as never before!
FDM is an indispensable tool for download acceleration. It splits files into several sections and then downloads them simultaneously allowing you to increase your download speed up to 600%.
FDM is available in 30 languages so there is bound to be a language for you.
