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, directories with authorization, MP3 audio and MPEG video content processing, and a large number of directory listing formats. 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, built-in download accelerator, scheduler pro, sounds on events, HTTPS support, queue processor, pipelining of ftp commands, 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.), command line parameters, and many others.
