RAR參數：

一、壓縮命令
1、將temp.txt壓縮為temp.rarrar a temp.rar temp.txt
2、將目前的目錄下所有檔案壓縮到temp.rarrar a temp.rar *.*
3、將目前的目錄下所有檔案及其所有子目錄壓縮到temp.rarrar a temp.rar *.* -r
4、將目前的目錄下所有檔案及其所有子目錄壓縮到temp.rar，並加上密碼123rar a temp.rar *.* -r -p123

二、解壓命令
1、將temp.rar解壓到c:\temp目錄rar e temp.rar c:\temprar e *.rar c:\temp(支援大量操作)
2、將temp.rar解壓到c:\temp目錄，並且解壓後的目錄結構和temp.rar中的目錄結構一

壓縮目錄test及其子目錄的檔案內容
Wzzip test.zip test -r -P
WINRAR A test.rar test -r

刪除壓縮包中的*.txt檔案
Wzzip test.zip *.txt -d
WinRAR d test.rar *.txt

重新整理壓縮包中的檔案，即添加已經存在於壓縮包中但更新的檔案
Wzzip test.zip test -f
Winrar f test.rar test

更新壓縮包中的檔案，即添加已經存在於壓縮包中但更新的檔案以及新檔案
Wzzip test.zip test -u
Winrar u test.rar test

移動檔案到壓縮包，即添加檔案到壓縮包後再刪除被壓縮的檔案
Wzzip test.zip -r -P -m
Winrar m test.rar test -r

添加全部 *.exe 檔到壓縮檔，但排除有 a或b
開頭名稱的檔案
Wzzip test *.exe -xf*.* -xb*.*
WinRAR a test *.exe -xf*.* -xb*.*

加密碼進行壓縮
Wzzip test.zip test
-s123。注意密碼是大小寫敏感的。在圖形介面下開啟帶密碼的壓縮檔，會看到+號標記（附圖1）。
WINRAR A test.rar test -p123
-r。注意密碼是大小寫敏感的。在圖形介面下開啟帶密碼的壓縮檔，會看到*號標記（附圖2）。

按名字排序、以簡要方式列表顯示壓縮包檔案
Wzzip test.zip -vbn
Rar l test.rar

鎖定壓縮包，即防止未來對壓縮包的任何修改
無對應命令
Winrar k test.rar

建立360kb大小的分卷壓縮包
無對應命令
Winrar a -v360 test

帶子目錄資訊解壓縮檔案
Wzunzip test -d
Winrar x test -r

不帶子目錄資訊解壓縮檔案
Wzunzip test
Winrar e test

解壓縮檔案到指定目錄，如果目錄不存在，自動建立
Wzunzip test newfolder
Winrar x test newfolder

解壓縮檔案並確認覆蓋檔案
Wzunzip test -y
Winrar x test -y

解壓縮特定檔案
Wzunzip test *.txt
Winrar x test *.txt

解壓縮現有檔案的更新檔案
Wzunzip test -f
Winrar x test -f

解壓縮現有檔案的更新檔案及新檔案
Wzunzip test -n
Winrar x test -u

批量解壓縮檔案
Wzunzip *.zip
WinRAR e *.rar
