WinRAR是什么就不用介绍了，如果你是计算机新手，请到Google.com搜索下。新版主要进行了大量Windows vista兼容性更新，包括新的基于CHM的HTML帮助文件、添加了ISO 13346 (UDF) 文件支持、Unicode ISO 9660 文件支持（可以处理ISO中非英文文件名）。更多更新请看Changlog。
尽管官方网站都没有正式发布正式版的消息，但是著名的下载站download却已经提供了下载地址。

Version 3.70 ChangeLogs:
1. Numerous Windows Vista compatibility changes:
a) help format changed from old HLP to newer HTML based CHM;
b) GUI self-extracting modules attempt to request for administrator permissions if they cannot create destination folder under current user account;
c) Log file rar.log and WinRAR theme files are stored in %APPDATA%\WinRAR folder instead of WinRAR program files folder.
Exported settings file settings.reg is also stored in %APPDATA%\WinRAR folder by default, but it is possible to select another folder in "Save WinRAR settings" and "Load WinRAR settings" dialogs.
WinRAR searches for registration key and settings.reg both in its program files folder and in %APPDATA%\WinRAR;
It is possible to set the string value "AppData" in Registry key HKEY_CURRENT_USER\Software\WinRAR\Paths to override the default %appdata%\WinRAR path for WinRAR settings.
For example, if you wish to store theme files in WinRAR folder, set this value to "c:\Program Files\WinRAR".
d) Vista compatibility changes in WinRAR shell integration;
e) New "Request administrative access" option in "Advanced" page
