This can be easily done using PowerShell, and rar.exe
which is part of WinRAR. Just edit the first three variables below according to your needs and run the script. You don't even need to save it as a script, just copy-paste the code into a PowerShell window, you can use the arrow keys to edit the variables (or edit it using notepad if you like) and then press enter when you're ready to run the script.
$winrar = "C:\Program Files\WinRAR\Rar.exe"
$passlist = @("pass1", "pass2", "pass3", "pass4")
$folder = "C:\Path\To\Folder"
cd "$folder"
foreach($file in (dir *.rar).Name) { "Checking $file..."; foreach($pass in $passlist) { .$winrar t -p"$pass" "$file" *>$null ; if($LASTEXITCODE -eq 0){ " → Password for $file is $pass"; break }}""}
This would give you an output which looks like:
Checking file1.rar...
→ Password for file1.rar is pass1
Checking file2.rar...
→ Password for file2.rar is pass2
Checking file3.rar...
→ Password for file3.rar is pass3
If there's something you don't understand in the code above, lemme know - happy to explain further. :)
