giFT Internet File Transfer (giFT) is a computer software daemon that allows several protocols to be used with a simple client having a graphical user interface (GUI). The client dynamically loads plugins implementing the protocols, as they are required.
Clients implementing frontends for the giFT daemon communicate with its process using a lightweight network protocol. This allows the networking protocol code to be completely abstracted from the user interface. The giFT daemon is written using relatively cross-platform C code, which means that it can be compiled for and executed on a big variety of operating systems. There are several giFT GUI front-ends for Microsoft Windows, Apple Macintosh, and Unix-like operating systems.
The name giFT (giFT Internet File Transfer) is a so-called recursive acronym, which means that it refers to itself in the expression for which it stands.
One of the biggest drawbacks of the giFT engine is that it currently lacks Unicode support, which prevents sharing files with Unicode characters in their file names (such as "ø","ä", "å", "é" etc.). Also, giFT lacks many features needed to use the gnutella network effectively.
Available protocols are:
Stable
OpenFT, giFT's own file sharing protocol
gnutella (used by FrostWire, Shareaza)
Turtle F2F
Beta version
FastTrack (used by Kazaa). The giFT plugin is giFT-FastTrack.
Alpha version
OpenNap
eDonkey network
Soulseek
giFT's sibling project is OpenFT, a peer-to-peer file-sharing network protocol that has a structure in which nodes are divided into 'search' nodes and 'index' supernodes in addition to common nodes. Since both projects are related very closely, when one says 'OpenFT', one can mean either one of two different things: the OpenFT protocol, or the implementation in the form of a plugin for giFT.
Although the name OpenFT stands for "Open FastTrack", the OpenFT protocol is an entirely new protocol design: only a few ideas in the OpenFT protocol are drawn from what little was known about the FastTrack protocol at the time OpenFT was designed.
