Free data compression software for windows

TrafficCompressor is a service that works like a universal compressing proxy server.
It compresses on-the-fly all data sent and received over the Internet, for example web pages, e-mail, Usenet, ICQ messages and so on. As a result your Internet traffic may be decreased by up to 40% - 60%.
TrafficCompressor can be especially valuable for the Internet users who pay for traffic, for example GPRS and EDGE Internet users.
TrafficCompressor is not intended for high-speed Internet connections and for the users who download a lot of already compressed files (GIF, JPEG images, ZIP, MP3, Flash, video files and so on).
Main features:
- Decreases text-based, HTML-based and other compressible Internet traffic.
- Supports any web browser, any e-mail, Usenet, IRC, ICQ client, Windows Messenger, most of FTP clients and other client Internet software.
- Supports GPRS, EDGE, GSM/CSD/HCSD, dial-up, ISDN, and any other Internet connection type.
- Supports any ISP (Internet Service Provider).
- Accelerates Internet connection with data compression and multithreading data transfer (similar to download managers).
- Uses persistent server connection technology to speed up a new network connection establishment.
- Makes Internet connection more stable. TrafficCompressor prevents data transmission (web browsing, e-mail receiving and so on) interruption when short modem connection breaks occur.
