Tixati 2.18

Tixati是一款基于BitTorrent协议的点对点文件分享工具，让使用者能加入群体下载大档案，提升传输效率。它的最大特色是进阶带宽图表，能分别显示协议与档案流量，并分类上传的分享与交易，让使用者清楚掌握网络使用状况。这款软件更新相当活跃，长期维护中，评价普遍不错，在同分类中属于热门选择。

这款工具适合需要精细控制带宽、或重视下载安全性的使用者，尤其在下载大型档案或调整上传比例时很实用。与uTorrent相比，Tixati更强调带宽管理，但界面可能较复杂；与Internet Download Manager这类下载管理器不同，它是P2P工具，用途各异。它是免费软件，但仅支援英文界面，中文使用者需留意语言上的门槛。

Tixati is a peer-to-peer file sharing application, which uses the popular BitTorrent protocol. The BitTorrent protocol allows numerous peers to form a collective swarm and download large files with maximum efficiency.Tixati uses advanced bandwidth charting of overall traffic and per-transfer traffic, with separate classification of protocol and file bytes and separate classification of outbound traffic for trading and seeding.

KEY FEATURES INCLUDE:

• Peer connection encryption for added security.
• Highly flexible bandwidth throttling, including trading/seeding proportion adjustment and adjustable priority for individual transfers and peers.
• Super-efficient peer choking/unchoking algorithms ensure the fastest downloads.

System Requirements: Windows 7/Vista/XP. 1 GHz+ Processor. Minimum 256 MB RAM. Display with 1024x768 resolution.
