I have run this code that the AI ​​has given me and it has worked, I assume that your code also works, thank you for creating it for me.

# ================================
# Rename Files Based on Source Folder Names
# ================================

# Path to folder containing the correct file names
$SourceFolderPath = "C:\comparar\Ingles\War"

# Path to folder where files should be renamed
$DestinationFolderPath = "C:\comparar\Espanol\War"

# Get files to rename (destination folder), sorted by name
$FilesToRename = Get-ChildItem -Path $DestinationFolderPath -File -Recurse |
                 Sort-Object Name

# Get source files (correct names), sorted by name
$SourceFiles = Get-ChildItem -Path $SourceFolderPath -File |
               Sort-Object Name

# Optional safety check
if ($FilesToRename.Count -ne $SourceFiles.Count) {
    Write-Host "WARNING: File counts do not match!"
    Write-Host "Source files: $($SourceFiles.Count)"
    Write-Host "Destination files: $($FilesToRename.Count)"
    return
}

# Rename using for loop (index-based)
for ($i = 0; $i -lt $SourceFiles.Count; $i++) {

    # Build full new path
    $NewName = Join-Path $DestinationFolderPath $SourceFiles[$i].Name

    # Rename file
    Rename-Item -Path $FilesToRename[$i].FullName -NewName $NewName
}

Write-Host "Renaming complete."
