A free C++ BitTorrent/HTTP/FTP Download Client

This is an old revision of the document!

Using eMule plugin

eMule is a freeware P2P, standalone, application client connecting to both the eDonkey Network and Kad Network. Visit eMule homepage.

The eMule plugin is a modded version of the client, made into a plugin for BitComet. Thus through this plugin BitComet enables cross-protocol and cross P2P-networks download and file-sharing.

Once the plugin is installed and enabled in BitComet's options, if you check the “Search for eDonkey download source” check-box on the properties page of the task, when you add a torrent in BitComet, it will automatically search for that resource in the eDonkey and Kad networks, too. Once the resource is found, BitComet will concurrently download from all available sources (BitTorrent, eMule and Kad peers) into the same file(s). BitComet will also upload the content when requested, to the eDonkey and Kad networks through eMule plugin, thus enabling true cross-protocol file-sharing. Although eMule is installed as a plugin for BitComet it can also be used as a standalone client (either by clicking the “Show eMule plugin” button on the Options page or by simply starting the executable file) in order to seek and retrieve files from the eDonkey Network.

“One advantage of eMule is a large user base, currently averaging 3 to 4 million people, which share some 4 billion files, which makes it excellent for finding rare content”¹⁾. Downloads from the eDonkey Network are usually slower that those in the BitTorrent Network, however for torrents which do not have any more seeds, eMule might prove to be the useful aid in finishing the download of those rare torrents you found so hard on some site.

Now eMule Xtreme mod is popular and being used as a plug-in in BitComet, but what is this Xtreme mod and what's the difference between normal eMule?
According to the Xtreme mod homepage: eMule Xtreme is a modification of the original eMule filesharing client. It is its aim to use the bandwidth more efficiently and to enlarge the range of the functions. We have paid special attention to create a stable, resource saving mod. The Comparison of eDonkey software can be found on wikipedia, and the changlog can be viewed here.

The main features²⁾ of Xtreme mod are:

Maella Bandwidthcontrol, caculates the real Overhead
NAFC (network adapter feedback control)
advanced Uploadbandwidththrottler with adjustable slotspeed
Xtreme Downloadmanager for a clever source-handling
improved Xtreme-Creditsystem
Powerrelease with dynamic Hide OS

Dynamic Leecher Protection (DLP)
Multi-threaded disc access with threading-queue

Add port mapping to eMule plugin

A high ID means the listen port is open and freely accessible by other clients that compatible with eMule, it's usually owned by users who have independent WAN IP.
A low ID means this port is blocked or cannot be reached. it's usually but not limited to owned by users who have only LAN IPs. So usually, low Id users have less download resources.
How WAN users say bye to LowID？

A low ID condition is usually caused by firewall. Closing firewall or make some changes in the BitComet listen port will get this condition solved. BitComet eMule plugin supports auto open TCP/UDP port. If you are using third party firewall, you only need to open the listen port for eMule plugin in the firewall settings. 【Read BitComet Create Firewall Rules】
