Portable of IDM's last version (December 20 release)
Internet Download Manager (IDM) is a tool to increase download speeds by up to 5 times, resume and schedule downloads. Comprehensive error recovery and resume capability will restart broken or interrupted downloads due to lost connections, network problems, computer shutdowns, or unexpected power outages. Simple graphic user interface makes IDM user friendly and easy to use.
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.
Version 5.12 adds complete Vista support, YouTube Grabber that can be used to download FLV videos from YouTube, Google Video, and MySpaceTV, redeveloped scheduler, MMS protocol support and the site grabber feature. This feature not only lets you download required files that are specified with filters, for example all pictures from a web site, or all audio files from a web site, but it also lets you download subsets of web sites, or complete web sites for mirroring or offline browsing. It's possible to schedule multiple grabber projects to run them once at a specified time, stop them at a specified time, or run periodically to synchronize changes. The new version also adds improved browser integration, redesigned and enhanced download engine, the unique integration into all latest browsers, improved toolbar, and a wealth of other improvements and new features.
