WinRAR 压缩文件管理工具
WinRAR 是一款功能强大的压缩包管理器，它是档案工具RAR 在 Windows 环境下的图形界面。该软件可用于备份数据，缩减电子邮件附件的大小，解压缩从 Internet 上下载的 RAR、ZIP及其它类型文件，并且可以新建 RAR 及 ZIP 格式等的压缩类文件。
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 5.20 beta 1
1. If Windows User Account Control prevents extracting or archiving
commands to create files in system protected folders, WinRAR attempts
to start its another copy with administrator privileges to complete
the operation. It is necessary to confirm privileges elevation
in response to User Account Control prompt to allow such second
WinRAR copy to run.
2. You can drag files in Explorer with right mouse button, drop them
to some folder and select WinRAR archiving commands in context menu
to create an archive with these files in the destination folder.
3. It is possible to use WinRAR.ini file instead of Registry to store
WinRAR settings. You may prefer such approach if you plan to install
WinRAR to removable media, such as USB flash drive, and then run it
on different computers.
See "WinRAR.ini file" topic in "Configuration settings" chapter
of WinRAR help for details.
4. Added extraction support for ZIP and ZIPX archives using
XZ compression algorithm.
5. If ZIP or ZIPX archive contains any compression algorithms except
usual "Store" or "Deflate", algorithm names are displayed
in "Version to extract" field of archive information dialog.
Algorithms with names unknown to WinRAR will be assigned "m"
name, where "num" is a compression algorithm numeric identifier.
6. "Open with WinRAR" command is available in Windows context menus
for archive formats supported by WinRAR. It can be turned off
with "Open with WinRAR (for usual archives)" option in WinRAR
"Settings/Integration/Context menu items..." dialog.
7. Command line RAR can read the default set of switches from rar.ini
file stored in RAR program folder. Previously it was possible to
define only the same set of switches for all RAR command with
"switches=" string. Now rar.ini also allows to specify
separate switch sets for individual RAR commands using
the following syntax:
switches_=
For example:
switches_a=-m5 -s
switches_x=-o+
8. Command "ch" supports switches -tl, -cu, -cl also for ZIP archives.
Previously "ch" allowed these switches only for RAR archive format.
9. For archive formats lacking file time information, such as .bz2,
.xz and .Z, WinRAR sets container archive modification time
to extracted files. It does not apply to tar.bz2, tar.xz and tar.Z,
which use file time stored in tar headers.
10. "Keep broken files" extraction option is supported for bzip2 archives.
11. WinRAR icon in Windows context menus is scaled up correctly
in high DPI screen modes such as 150% or 200% of normal text size.
12. It is possible to disable WinRAR "Benchmark" command with
"Benchmark" variable of HKEY_CURRENT_USERSoftwareWinRARPolicy
Registry key. In multi-user environment "Benchmark" command might
abuse shared computational resources. See "Registry variables" topic
in "Configuration settings" chapter of WinRAR help for more details.
13. Additionally to "sfxcmd" variable containing the entire command line,
SFX module sets "sfxpar" variable containing command line parameters
only, without leading SFX module name. These variables are set before
starting a program specified in "Setup" command.
14. File overwrite prompt in console RAR displays the size and modification
time for existing and new files.
15. When archiving from stdin with -si switch, RAR sets the current system
time to modification time of archived file. Previous version did not
set this time at all.
16. It is possible to use -si and -v switches together. Previous
versions did not allow to create volumes when archiving from stdin.
17. Warning is issued when starting unpacking 4 GB or larger file
from RAR or ZIP archive to FAT32 patition, so user may cancel
the operation. FAT32 does not support files of such size.
Also this warning is issued when starting to create RAR archive
with "Store" (-m0) method if estimated archive size is 4 GB or more.
18. "Select all" button in "Settings/Integration" dialog is renamed to
"Toggle all". Now it deselects archive formats if all they are
already selected.
19. "Delete archive" extraction option correctly removes all .zip and .7z
volumes. Previously it removed only the first volume in the set
for these archive formats.
