例如已经获取某文件的扩展名为 rar ，如何取得关联程序所在路径（例如：C:\Program Files\WinRAR\WinRAR.exe）？请指教。


根据楼下介绍方法已解决，多谢指点。解决后的代码如下：
@echo off if "%1"=="" echo 请把文件或文件夹拖到我身上，便可创建快捷方式到桌面上。&&pause>nul&&exit set "a=%1" set "name=%~n$a:1%" set "ext=%~x$a:1%" if "%ext%"=="" goto FOLDER for /f "tokens=2 delims==" %%b in ('assoc %ext%') do ( for /f "tokens=2 delims==" %%c in ('ftype %%b') do set "d=%%c" ) set "d=%d:"=%" set "n=%d%" set "n=%n:~-1%" if "%n%"=="*" (set "d=%d:~0,-5%") else (set "d=%d:~0,-2%") set "e=0" if /i "%ext%"==".vbs" set "e=2" if /i "%ext%"==".js" set "e=3" if /i "%ext%"==".doc" set "d=%d:~0,-5%" && set "e=1" if /i "%ext%"==".xls" set "e=1" if /i "%ext%"==".ppt" set "e=1" if /i "%ext%"==".bat" set "d=%SystemRoot%\system32\SHELL32.dll" && set "e=71" if /i "%ext%"==".cmd" set "d=%SystemRoot%\system32\SHELL32.dll" && set "e=71" :URL echo >"%userprofile%\桌面\%name%.url" echo URL="%a%" >>"%userprofile%\桌面\%name%.url" echo IconIndex=%e% >>"%userprofile%\桌面\%name%.url" echo IconFile=%d% >>"%userprofile%\桌面\%name%.url" exit :FOLDER set "d=%SystemRoot%\system32\SHELL32.dll" dir /a:d "%a%"|find.exe "DIR" >nul if not errorlevel 1 (set "e=3") else (set "e=0") goto URL

@echo off
for /f "tokens=2 delims==" %%a in ('assoc .rar') do (
ftype %%a
)
pause
