Tutorial – Using WinRAR command-line tools

When you install WinRar, two command-line tools are also installed, rar.exe and unrar.exe. They will be located in C:\Program Files\WinRAR by default.

Here’s an example of how to extract the contents of a single rar file:

  1. open a command prompt
    (Windows 2000/xp, choose start->programs->accessories->Command Prompt)
  2. add the winrar tools to the path:
    c:\> set path="C:\Program Files\WinRAR\";%path%
  3. switch to the directory where you want your files to extract to:
    c:\> cd /d z:\some_folder
  4. use unrar to extract the file:
    z:\some_folder> unrar e c:\some_rar_file.rar

You can of course wrap all of this into a batch file that loops through all of the .rar files in a folder. Here’s a quicky sample (doesn’t handle spaces in .rar file names):

@REM ------- BEGIN demo.cmd ----------------
@setlocal
@echo off
set path="C:\Program Files\WinRAR\";%path%
for /F %%i in ('dir /s/b *.rar') do call :do_extract "%%i"
goto :eof

:do_extract
echo %1
mkdir %~1.extracted
pushd %~1.extracted
unrar e %1
popd

REM ------- END demo.cmd ------------------

For detailed information on windows batch files, please see:


OSX documentation [new]

  1. Open a terminal window.
  2. In the terminal window, navigate to the folder containing your .rar files:
    cd /<path-to-files>
  3. Run the following command:
    for i in *.rar; do unrar e "$i"; done

    Note: “unrar” may need to be replaced with the full path to your unrar executable. For example, if unrar is installed in /usr/local/bin, the command becomes:

    for i in *.rar; do /usr/local/bin/unrar e "$i"; done

    OSX unrar is available from RAR Labs, here

    Instead of bloating the path, you could also symlink the .exe files to a common and suitable location already in the path. If you are still running XP you could physically copy them there, and again after each update.

      This is true. However, the script we supply has @setlocal before modifying the path, so the change does not affect the user’s environment variables once the script completes.
