Am trying to extract a RAR file to a directory (C:\autoexe\source). Here the "autoexe" folder name changes everyday. The fullname does not change, the constant thing is "auto" in the string "autoexe", the exe part changes. I tried the below
for /f "delims=" %%a in ('dir /b "%cd%\samples\package.rar"') do start "" "%ProgramFiles%\WinRAR\WinRAR.exe" x -ibck "%cd%\samples\package.rar" *.* "%cd%\auto * \source"
This commented batch code with error handling should do the job:
@echo off
rem Get name of first non hidden subfolder starting with auto in current folder.
for /D %%I in (auto*) do set "FolderName=%%I" & goto CheckArchive
echo Error: There is no auto* folder in: "%CD%"
echo/
pause
goto :EOF
:CheckArchive
if exist "samples\package.rar" goto ExtractArchive
echo Error: There is no file "package.rar" in subfolder "samples" of
echo folder: "%CD%"
echo/
pause
goto :EOF
:ExtractArchive
"%ProgramFiles%\WinRAR\UnRAR.exe" x -c- -idq -y -- "samples\package.rar" "%FolderName%\"
if not errorlevel 1 goto :EOF
echo/
echo/
pause
Read text file Rar.txt in program files folder of WinRAR for details on the used switches on UnRAR command line or run UnRAR.exe from within a command prompt window without any option to get displayed a brief help on how to use this freeware console application.
For understanding the used commands and how they work, open a command prompt window, execute there the following commands, and read entirely all help pages displayed for each command very carefully.
