WinRAR 3.70 Final

WinRAR is a 32-bit Windows version of RAR Archiver, an archiver and archive manager. RAR files can usually compress content by 8 percent to 15 percent more than ZIP files can. WinRAR's main features include strong general and multimedia compression, the ability to process non-RAR archive formats, ZIP compression and decompression, support for long filenames, programmable self-extracting archives (SFX), repair of damaged archives, authenticity verification, embedded file comments, and encryption. Unicode is supported in archive filenames, allowing non-English filenames to be handled painlessly. You can manipulate the parameters of many archives at once and view a volume sequence as a single archive. WinRAR can convert other archive formats to RAR and search for specified text and files in archives.

WINRAR 是现在最好的压缩工具，界面友好，使用方便，在压缩率和速度方面都有很好的表现。其压缩率比之 WINZIP 之流要高。RAR 采用了比 Zip 更先进的压缩算法，是现在压缩率较大、压缩速度较快的格式之一。 主要特点：对 RAR 和 ZIP 的完全支持； 支持 ARJ、CAB、LZH、ACE、TAR、GZ、UUE、BZ2、JAR、ISO 类型文件的解压；多卷压缩功能；创建自释放文件，可以制作简单的安装程序，使用方便；强大的档案文件修复功能，最大限度恢复损坏的 rar 和 zip 压缩文件中的数据，如果设置了恢复记录，甚至可能完全恢复等等……

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
         of "Advanced SFX options" allows to create SFX archive,
         which will request the administrative access when started
         in Windows Vista.

         Command line equivalent of this option is -iadm switch.

   2. Added support for ISO 13346 (UDF) file format. This format
      is frequently used in ISO images of DVD disks.

   3. Added Unicode support for ISO 9660 files, so WinRAR should
      handle non-English file names in .iso files better.

   4. Design changes in window displaying archiving and extraction
      progress:

      a) it provides more space for file names, allowing lengthy names;

      b) it displays the current archive name in separate line,
         allowing much longer archive names than before;

      c) when archiving, it displays the current compression ratio
         in separate line;

      d) it can use both standard Windows and classic WinRAR progress bars.
         Turn on "Windows progress bars" option in WinRAR "Settings/General"
         dialog to use standard progress bars. By default this option is
         on if some Windows visual style is active and off if Windows Classic
         theme is selected.

         Windows progress bars are two color only, so they do not indicate
         the current compression ratio. But now the ratio is displayed
         in separate line;

      e) "Mode..." button moved to bottom of window.

   5. GUI self-extracting modules support following command line
      switches:

      -d     set the destination path
      -p      specify a password
      -s           silent mode, hide all
      -s1          same as -s
      -s2          silent mode, hide start dialog
      -sp     specify parameters for setup program

   6. GUI self-extracting modules do not pass the entire command line
      to setup program like they did in previous versions.
      If you need to get access to entire command line of SFX archive,
      parse sfxcmd environment variable which contains this command line.

   7. New switch -sc[objects] allowing to select character
      sets for archive comments and list files. It replaces -fcu switch
      introduced in RAR 3.60, which was removed from list of supported
      switches. Now you need to specify -scuc instead of -fcu to use
      Unicode comments. Unlike -fcu, -sc also supports OEM and ANSI charset.

   8. New "Save archive copy as..." command in "File" menu.
      This command may be useful if you opened an archive from Internet
      directly in WinRAR and then decided to save it on local disk.

   9. "Word wrap" command added to "View" menu of WinRAR internal viewer,
      so you can change the wrapping mode of already opened viewer window.

      State of this option is not stored between viewing sessions.
      If you need to change the default word wrap mode, use WinRAR
      "Settings/Viewer" dialog.

  10. Buttons "Up" and "Down" added to "Organize profiles" dialog.
      Using these buttons you can change position of selected profile
      in the list.

  11. Operation progress is displayed when adding the recovery record.

  12. If WinRAR is minimized to tray and mouse is over its icon,
      WinRAR diplays a message about the current operation progress.
      In previous versions it included only percent done, now it also
      contains the time left information.

  13. Console RAR displays "Calculating the control sum" message
      when calculating CRC32 control sum for newly created RAR volume.
      Previous versions also calculated the volume control sum,
      but did it silently.

  14. Archives history list in "File" menu allows Unicode names,
      providing more reliable support for non-English archive names.

  15. Stack overflow vulnerability has been corrected in password
      processing module of console RAR and UnRAR. GUI WinRAR is not
      affected. We are thankful to the iDEFENSE LABS for reporting this bug.

最新亮点：

1. 多线程版本的 RAR 压缩算法提高了在有数个 CPU、双核 CPU 和使用超线程技术的处理器的计算机上的压缩速度。多线程默认被启用，但是你可以在 “设置”对话框的“常规”部分中禁用它。在命令行模式你可以使用 -mt<线程 开关控制多线程。

2. WinRAR 可以显示文件夹树面板来在磁盘和文件夹目录中导航。使用“选项/文件夹树”子菜单启用文件夹树。它能在文件和压缩文件管理模式下被单独配置。文件夹树代替了以前在“文件”菜单中的“浏览文件夹”命令并使用了它的Ctrl+T 键盘快捷键。

3. 新的 WinRAR “重命名”命令也能处理 ZIP 压缩文件了。以前版本仅能处理RAR 压缩文件。

4. 添加了对使用 "-lh7" 算法创建的 LZH 压缩文件的解压。

5. 在“设置/压缩”对话框中新的“从解压路径移除重复的文件夹”选项。如果此选项打开，你解压的压缩文件的根目录没有文件而只有一个“somename”文 件夹并且目标文件夹是新建的或空的并以 '/somename' 结尾, WinRAR 会从 'somename/somename' 的结果路径中排除一个 'somename'。

6. 在“设置/压缩”对话框中的新的“定义卷大小...”按钮。此按钮激活“定义卷大小”对话框。这里你可以自定义预定义的卷大小，和压缩对话框中的“分割卷, 单位字节”关联。

7. 对某些数据类型 RAR 生成压缩文件的速度增加。根据数据的类型和大小，压缩文件会减小 5 - 15%。

8. 在解压对话框中和命令行的 -or 开关的新的“自动重命名”选项来自动重命名同名文件已经存在的解压文件。你也可以从覆盖确认提示中选择“全部重命名”按钮直接启用自动重命名模式。重命名 文件将得到象 'filename(N).txt' 的名字，'filename.txt' 的位置是原始的文件名，'N' 是数字。

9. 在解压对话框的“高级”部分的“设置修改时间”选项也可用于 ZIP 压缩文件。以前它仅可用于 RAR 压缩文件来修改。

10. “多线程”选项添加到“性能和硬件测试”命令中，这样你可以比较常规和多线程版本的 RAR 压缩算法的性能。

11. 新的 'ch' (改变压缩文件参数) 命令行模式命令。它的目的是应用开关-av, -tl and -cl 到压缩文件。

12. 新的 'cv' 命令行模式命令。它提供命令行界面到 WinRAR 的 "转换压缩文件" 命令。它仅支持 winrar.exe，而不支持 rar.exe。

13. 新的命令行 -sl<大小 和 -sm<大小 开关设置处理的文件的大小限制。

14. 新的命令行 -fcu[文件] 开关允许从 Unicode 文件读取压缩文件注释。它允许修改 "cw" 命令的行为，设置注释输出格式为 Unicode。

15. 当使用不带参数的 -ms 开关时，7Z 添加到不压缩存储的格式列表中。

16. 开关 -e[+]<属性 现在被大多数命令行操作，包括解压和删除文件，支持。以前它仅被压缩命令支持。

17. 在压缩对话框的压缩文件名中，在解压对话框的目标路径 中，在 WinRAR设置的“压缩”和“路径”页的文件夹名都允许使用环境变量。例如，你可以在“临时文件文件夹” 区域中输入 '%temp%'。
