Download manager Guide, Meaning , Facts, Information and Description

A download manager is a program designed to download files from the Internet, unlike a web browser, which is mainly intended to browse pages on the WWW (with file downloading being of secondary importance). A download manager is also designed to download files from slow connections, which can cause problems with web browsers.

There are several things that web browsers are not very good at. That's where the download managers enter the equation:

• pausing the downloading of large files.
• resuming broken or paused downloads (especially for large files, like LiveCDs).
• downloading files on poor connections.
• downloading several files from a site automatically according to simple rules (file types, updated files, etc.).
• automatic recursive downloads (mirroring).
• scheduled downloads (including, automatic hang-up and shutdown).
• searching for mirror sites, and the handling of different connections to download the same file more quickly.
• optional integration with a web browser, automatically taking over any download of user-specified file types.

Download managers are necessary for every heavy Internet user. For dial-up users, they can automatically dial the ISP at night, when rates or tariffs are usually lower, download the specified files, and hang-up. They can record which links the user clicks on during the day, and queue these files for later download. For broadband users, download managers can help download 100+ megabyte files by resuming broken downloads, by limiting the download capacity used, so that user's browsing is not affected much and the server is not overloaded, or by automatically browsing a site and downloading content specified by user (photo galleries, MP3 collections, etc.), including automatically downloading whole sites and regularly updating them.

Most download managers today integrate seamlessly with popular web browsers, and are extremely easy to use. Clicking on a link in a browser automatically starts the download in the download manager. For power users, additional features are available, such as scheduling, traffic shaping, virus-checking, cataloguing, etc.

Some of them include spyware or adware bundled with the program.

Among the most popular download managers are Download Accelerator, ReGet, GoZilla, FlashGet, GetRight, Internet Download Manager and Net Transport. Other examples are QuickDownloader (Java based) and NetAnts. Offline Explorer is the most powerful program for recursive site downloads. For command-line users, there are wget and cURL, in which most of the advanced functionality are enabled by various command-line parameters.

Related to download managers are two other breeds of Internet programs - file-sharing peer-to-peer applications (KaZaA, eMule, BitTorrent, gnutella) and stream recorders (such as StreamBox VCR).
