ChatGPT回答的，使用 PowerShell

# Define the folder path
$folderPath = "C:\YourFolderPath"

# Get all files recursively in the folder and subfolders
$files = Get-ChildItem -Path $folderPath -File -Recurse

# Define the date format for renaming
$dateSuffix = (Get-Date).ToString("yyyyMMdd")

# Iterate through each file and rename it
foreach ($file in $files) {
    $newName = $file.Name + ".$dateSuffix"
    $newPath = Join-Path -Path $file.DirectoryName -ChildPath $newName
    Rename-Item -Path $file.FullName -NewName $newName -ErrorAction SilentlyContinue
}

Write-Host "All files renamed successfully with date suffix $dateSuffix."
