Internet Download Manager has a smart download logic accelerator that  features intelligent dynamic file segmentation and safe multipart  downloading technology to accelerate your downloads. Unlike other  download accelerators and managers that segment files before downloading  starts, Internet Download Manager segments downloaded files dynamically  during download process. Internet Download Manager reuses available  connections without additional connect and login stages to achieve  better acceleration performance.
Internet Download Manager  supports proxy servers, ftp and http protocols, firewalls, redirects,  cookies, authorization, MP3 audio and MPEG video content processing. IDM  integrates seamlessly into Microsoft Internet Explorer, Netscape, MSN  Explorer, AOL, Opera, Mozilla, Mozilla Firefox, Mozilla Firebird, Avant  Browser, MyIE2, and all other popular browsers to automatically handle  your downloads.
You can also drag and drop files, or use Internet  Download Manager from command line. Internet Download Manager can dial  your modem at the set time, download the files you want, then hang up or  even shut down your computer when it's done.
Other features  include multilingual support, zip preview, download categories,  scheduler pro, sounds on different events, HTTPS support, queue  processor, html help and tutorial, enhanced virus protection on download  completion, progressive downloading with quotas (useful for connections  that use some kind of fair access policy or FAP like Direcway, Direct  PC, Hughes, etc.), built-in download accelerator, and many others.
