根据文件名(日期) -powershell更改文件夹结构年>月

# 设置源文件夹路径和目标文件夹路径
$sourceFolder = "C:\SourceFolder"
$targetFolder = "C:\TargetFolder"

# 获取源文件夹中的所有文件名
$fileNames = Get-ChildItem -Path $sourceFolder | Select-Object -ExpandProperty Name

# 遍历每个文件名
foreach ($fileName in $fileNames) {
    # 提取日期信息
    $date = $fileName.Substring(0, 6)  # 假设文件名的日期格式为YYMMDD

    # 创建年份文件夹和月份文件夹
    $yearFolder = Join-Path -Path $targetFolder -ChildPath $date.Substring(0, 2)
    $monthFolder = Join-Path -Path $yearFolder -ChildPath $date.Substring(2, 2)
    New-Item -ItemType Directory -Path $yearFolder -ErrorAction SilentlyContinue
    New-Item -ItemType Directory -Path $monthFolder -ErrorAction SilentlyContinue

    # 移动文件到对应的年份文件夹和月份文件夹中
    Move-Item -Path (Join-Path -Path $sourceFolder -ChildPath $fileName) -Destination $monthFolder
