WinRAR 7.21 B1 / 7.20

WinRAR 7.21 B1 / 7.20

WinRAR is a powerful archive manager. It can backup your data and reduce the size of email attachments, decompress RAR, ZIP and other files downloaded from Internet and create new archives in RAR and ZIP file format

Features of WinRAR:
• Using WinRAR puts you ahead of the crowd when it comes to compression by consistently making smaller archives than the competition, saving disk space and transmission costs.
• WinRAR provides complete support for RAR and ZIP archives and is able to unpack CAB, ARJ, LZH, TAR, GZ, ACE, UUE, BZ2, JAR, ISO, 7Z, Z archives.
• WinRAR offers a graphic interactive interface utilizing mouse and menus as well as the command line interface.
• WinRAR is easier to use than many other archivers with the inclusion of a special “Wizard” mode which allows instant access to the basic archiving functions through a simple question and answer procedure. This avoids confusion in the early stages of use.
• WinRAR offers you the benefit of industry strength archive encryption using AES (Advanced Encryption Standard) with a key of 128 bits.
• WinRAR supports files and archives up to 8,589 billion gigabytes in size. The number of archived files is, for all practical purposes, unlimited.
• WinRAR offers the ability to create selfextracting and multivolume archives.
Recovery record and recovery volumes allow to reconstruct even physically damaged archives.
• WinRAR features are constantly being developed to keep WinRAR ahead of the pack.

Version 7.21 beta 1

1. WinRAR properly recognizes archives with a wrong file extension,
containing an archive in another format stored without compression.

For example, if host.rar, storing nested.zip inside, was renamed to
host.zip, previous versions could display nested.zip contents
when opening such host.zip. This version displays host.zip contents.

2. Similarly to Windows Explorer, the first click on size and time columns
in WinRAR file list sets the reverse sort mode with largest and latest
files at the top.

3. Switch -s=e performs the case insensitive file extension comparison
in Windows. Unlike previous versions, solid statistics isn’t reset
anymore for file extensions differing only by case.

4. If self-extracting archive attempts to extract files to a folder
requring administrator rights and elevation prompt is cancelled by user,
the archive quits silently instead of issuing the folder access error.

5. Bugs fixed:

a) WinRAR 7.20 couldn’t unpack ZIP archives containing file comment
fields;

b) switch -tl didn’t set the latest time when used with RAR 7.20
“ch” command;

c) extraction command didn’t automatically replace device names
like “aux”, when unpacking archives containing such reserved names;

d) if folder shortcut was double clicked in “Save WinRAR settings as”
dialog when exporting WinRAR settings, folder shortcut itself was
overwritten with settings data instead of opening a target folder.

版本 7.20

1. 改进删除实心 RAR 压缩包中的文件时的性能:

a) 如果删除文件后没有非零文件,则不会执行压缩包重新压缩;

b) 删除文件之前的部分压缩包内容将原样复制,不进行重新打包。如有必要,其内容将解压缩到内存中,但不会重新压缩;

c) 半实心压缩包的处理仅涉及包含已删除文件的实心块。未受影响的实心块将原样复制。

2. “按掩码生成压缩包名称”归档选项和 -ag 命令行开关:

a) 新增“K”格式字符,用于定义当前星期几的名称(文本字符串);

b) 新增“O”格式字符,用于定义当前月份的名称(文本字符串),与格式字符编号无关。

与“MMM”掩码不同,

它允许使用长度超过或短于 3 个字符的名称,

例如 -agOO;

c) 超出可用字段宽度的格式字符过多
现在将被忽略,而不是附加到归档名称。

因此,可以通过提供长度等于或超过最长名称的格式字符来使用完整的月份或星期名称,

例如,星期名称可以使用 -agKKKKKKKKKKK。

3. 命令行 -s 开关:

a) 开关 -s 接受以“=”字符开头的可选参数。

开关 -s、-se、-sv、-sv-、-s- 已替换为 -s=f、-s=e、

-s=v、-s=d、-s=-。这些开关的先前版本在当前版本中仍然受支持,但将来可能会被移除。

允许在同一个开关中组合多个修饰符,

例如 -s=e100f。

b) 新增开关 -s=r 会在将新文件添加到现有归档之前重置 Solid 统计信息。

4. 开关 -tk 现在接受 YYYYMMDDHHMMSS 格式的可选日期参数。

如果在修改归档文件时不带此参数,

则会保留原始归档时间。

如果存在可选参数,

则会将其赋值给归档文件的修改时间。

允许在日期字符串中插入分隔符,例如“-”或“:”,

并省略尾随字段。例如,开关 -tk2025-06-01 是正确的。

5. “时间”页面的“设置归档时间”选项中添加了“指定时间”。

允许将手动输入的时间赋值给新创建或修改的归档文件。

6. “生成报告”命令添加了 UTF-8 输出格式和字节顺序标记选项。

7. “设置/集成/上下文菜单项…”对话框中的“SFX 归档文件检查位置”组添加了“云文件”选项。

如果关闭此选项,WinRAR shell 扩展程序将不会尝试

在右键单击本地不可用的可执行云文件时检测压缩文件是否为自解压文件。

此检测涉及数据读取,对于此类文件可能会很慢。

此选项依赖于云存储提供商返回的文件属性,

如果所需的属性不受特定云服务支持,则可以忽略此选项。

8. “搜索结果”对话框底部的“复制到剪贴板”按钮

会将“查找文件”命令的当前结果复制到剪贴板。

9. 打开包含大量文件和文件夹的大型压缩文件所需的时间更短。

对于包含数百万个文件的 ZIP 压缩文件,这一点尤为明显。

10. 提高了 TAR 和基于 TAR 的压缩文件(例如 .tar.gz 或 .tar.xz)的提取速度。

对于寻道速度较慢的硬盘驱动器以及包含大量文件的大型压缩文件,这一点尤为明显。

11. SFX 模块设置 sfxnamenoext 环境变量,其中包含

SFX 归档名称(不包含路径和扩展名)。它允许将归档名称附加到用户定义的目标路径,例如:

Path=c:\Util\%sfxnamenoext%”

12. “minsize” 参数(定义最小文件引用大小)在 -oi[0-4][:] 开关中,现在可以包含可选的尾随单位大小字符。因此,-oi:1m 等效于 -oi:1048576。

13. 开关 -x 可以识别使用 Windows 和 Unix 风格路径分隔符的排除路径,因此 -xfolder\file 和 -xfolder/file 的效果相同。

以前只有 -xfolder\file 会排除文件。

14. 已修复的错误:

a) 如果启用了“将每个文件放入单独的归档”选项,则归档对话框中的“要排除的文件”字段对于除第一个 ZIP 归档之外的所有归档都会被忽略;

b) 处理“转换归档”命令时,密码提示中的“用于所有归档”选项仅适用于加密的压缩文件

文件名加密的压缩文件无法启用

转换未加密文件名的压缩文件时。
