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 是現(xiàn)在最好的壓縮工具，界面友好，使用方便，在壓縮率和速度方面都有很好的表現(xiàn)。其壓縮率比之 WINZIP 之流要高。RAR 采用了比 Zip 更先進的壓縮算法，是現(xiàn)在壓縮率較大、壓縮速度較快的格式之一。 主要特點：對 RAR 和 ZIP 的完全支持； 支持 ARJ、CAB、LZH、ACE、TAR、GZ、UUE、BZ2、JAR、ISO 類型文件的解壓；多卷壓縮功能；創(chuàng)建自釋放文件，可以制作簡單的安裝程序，使用方便；強大的檔案文件修復(fù)功能，最大限度恢復(fù)損壞的 rar 和 zip 壓縮文件中的數(shù)據(jù)，如果設(shè)置了恢復(fù)記錄，甚至可能完全恢復(fù)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
-p
-s silent mode, hide all
-s1 same as -s
-s2 silent mode, hide start dialog
-sp
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
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.
最新亮點：
1. 多線程版本的 RAR 壓縮算法提高了在有數(shù)個 CPU、雙核 CPU 和使用超線程技術(shù)的處理器的計算機上的壓縮速度。多線程默認被啟用，但是你可以在 “設(shè)置”對話框的“常規(guī)”部分中禁用它。在命令行模式你可以使用 -mt<線程 開關(guān)控制多線程。
2. WinRAR 可以顯示文件夾樹面板來在磁盤和文件夾目錄中導(dǎo)航。使用“選項/文件夾樹”子菜單啟用文件夾樹。它能在文件和壓縮文件管理模式下被單獨配置。文件夾樹代替了以前在“文件”菜單中的“瀏覽文件夾”命令并使用了它的Ctrl+T 鍵盤快捷鍵。
3. 新的 WinRAR “重命名”命令也能處理 ZIP 壓縮文件了。以前版本僅能處理RAR 壓縮文件。
4. 添加了對使用 "-lh7" 算法創(chuàng)建的 LZH 壓縮文件的解壓。
5. 在“設(shè)置/壓縮”對話框中新的“從解壓路徑移除重復(fù)的文件夾”選項。如果此選項打開，你解壓的壓縮文件的根目錄沒有文件而只有一個“somename”文 件夾并且目標(biāo)文件夾是新建的或空的并以 '/somename' 結(jié)尾, WinRAR 會從 'somename/somename' 的結(jié)果路徑中排除一個 'somename'。
6. 在“設(shè)置/壓縮”對話框中的新的“定義卷大小...”按鈕。此按鈕激活“定義卷大小”對話框。這里你可以自定義預(yù)定義的卷大小，和壓縮對話框中的“分割卷, 單位字節(jié)”關(guān)聯(lián)。
7. 對某些數(shù)據(jù)類型 RAR 生成壓縮文件的速度增加。根據(jù)數(shù)據(jù)的類型和大小，壓縮文件會減小 5 - 15%。
8. 在解壓對話框中和命令行的 -or 開關(guān)的新的“自動重命名”選項來自動重命名同名文件已經(jīng)存在的解壓文件。你也可以從覆蓋確認提示中選擇“全部重命名”按鈕直接啟用自動重命名模式。重命名 文件將得到象 'filename(N).txt' 的名字，'filename.txt' 的位置是原始的文件名，'N' 是數(shù)字。
9. 在解壓對話框的“高級”部分的“設(shè)置修改時間”選項也可用于 ZIP 壓縮文件。以前它僅可用于 RAR 壓縮文件來修改。
10. “多線程”選項添加到“性能和硬件測試”命令中，這樣你可以比較常規(guī)和多線程版本的 RAR 壓縮算法的性能。
11. 新的 'ch' (改變壓縮文件參數(shù)) 命令行模式命令。它的目的是應(yīng)用開關(guān)-av, -tl and -cl 到壓縮文件。
12. 新的 'cv' 命令行模式命令。它提供命令行界面到 WinRAR 的 "轉(zhuǎn)換壓縮文件" 命令。它僅支持 winrar.exe，而不支持 rar.exe。
13. 新的命令行 -sl<大小 和 -sm<大小 開關(guān)設(shè)置處理的文件的大小限制。
14. 新的命令行 -fcu[文件] 開關(guān)允許從 Unicode 文件讀取壓縮文件注釋。它允許修改 "cw" 命令的行為，設(shè)置注釋輸出格式為 Unicode。
15. 當(dāng)使用不帶參數(shù)的 -ms 開關(guān)時，7Z 添加到不壓縮存儲的格式列表中。
16. 開關(guān) -e[+]<屬性 現(xiàn)在被大多數(shù)命令行操作，包括解壓和刪除文件，支持。以前它僅被壓縮命令支持。
17. 在壓縮對話框的壓縮文件名中，在解壓對話框的目標(biāo)路徑 中，在 WinRAR設(shè)置的“壓縮”和“路徑”頁的文件夾名都允許使用環(huán)境變量。例如，你可以在“臨時文件文件夾” 區(qū)域中輸入 '%temp%'。
