流行好用的压缩工具，支持鼠标拖放及外壳扩展，完美支持 ZIP 档案，内置程序可以解开 CAB、ARJ、LZH、TAR、GZ、ACE、UUE、BZ2、JAR、ISO 等多种类型的压缩文件；具有估计压缩功能，你可以在压缩文件之前得到用 ZIP 和 RAR 两种压缩工具各三种压缩方式下的大概压缩率；具有历史记录和收藏夹功能；压缩率相当高，而资源占用相对较少、固定压缩、多媒体压缩和多卷自释放压缩是大多 压缩工具所不具备的。 Version 5.21 beta 1 1. "Drag and drop context menu" options in "Settings/Integration/ Context menu items" dialog allow to disable WinRAR archiving and extraction commands in context menu displayed after dragging and dropping files with right mouse button. 2. If winrar.ini file is present in the same folder as WinRAR installer, winrar.ini will be copied to WinRAR program folder after completing installation. 3. While previous versions could produce RAR5 volumes of slightly smaller than requested size sometimes, such situation is less likely now. In most cases volume size equals to specified by user. 4. Bugs fixed: a) WinRAR 5.20 issued unnecessary user account control (UAC) prompt, when running an executable from archive stored in UAC protected folder. Since nothing is extracted to folder containing an archive in such case, UAC prompt is not needed; b) WinRAR could overwrite files with read-only attribute only when unpacking RAR and ZIP archive formats. Now it is also implemented for other archive formats supported by WinRAR; c) "Elapsed time" and "Time left" were displayed incorrectly when applying "Convert" command to multiple archives and enabling "Add recovery record" option. http://www.rarlab.com/rar/wrar521b1.exe http://www.rarlab.com/rar/winrar-x64-52b3.exe WinRAR 5.21 Beta 1 发布下载地址
