WinRAR 5.0.0 官方版更新，第三个Beta版放出下载，解决了Beta2版中存在的问题，同时针对XP（最大压缩字典在32位Windows XP中降低至128MB）等环境进行了优化。

WinRAR是一款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。

1. Fixed XZ archive support, which did not work in beta 2.

2. "Convert" command did not allow to use compression dictionaries exceeding 4 MB.

3. If both encryption password and archive comment were specified when creating RAR archive, archive comment was not added.

4. "View as Unicode (UTF-8)" command in internal viewer did not work, so UTF-8 files were displayed correctly only if their encoding was detected by viewer automatically.

5. Maximum compression dictionary size when running in Windows XP x86 is reduced to 128 MB. WinRAR cannot allocate enough memory to create archives with 256 MB dictionary in Windows XP x86.

6. Corrections in relative path processing, such as "..\arcname.rar" name in archiving dialog or "WinRAR foldername" in the command line.
