# Recursively search for files and directories in the root directory
$items = Get-ChildItem -Path $rootDirectory -Recurse

# Loop through each item (file or directory) and rename if necessary
foreach ($item in $items) {
    # Check if the item's name contains the old word
    if ($item.Name -match $oldWord) {

        $newName = $item.Name -replace $oldWord, $newWord
