Question

我需要一个 PS 脚本来删除目录的所有子文件夹，除了那些：

过去 7 天的所有内容
上个月每周的一个最新文件夹
过去一年每个月的一个最新文件夹

我是 PS 的新手，并且已经花了很多时间在挣扎中。讨厌哭求救命，但我想，这是正确的时刻。

谢谢！

现在完成（:

# Initiate the intervals in days by which the folders will be kept
$savedays = @('7', '14', '21', '30', '60', '90', '120', '150', '180', '210', '240', '270', '300', '330', '360')

# initiate array of folders to be deleted
$killlist = @()

# Start a for loop until hitting the one before last element of $savedays
For ($i=0;$i -lt ($savedays.Length -1 ); $i++) {

    # Get list of folders in the $path_main
    $killlist += @(Get-ChildItem $path_main |
        # Newest first
        Sort-Object -Property LastWriteTime -Descending | 
        # Between one and next elevement of #savedays, i.e. between 7 days ago and 14 days ago
        Where-Object { $_.LastWriteTime -lt (get-date).AddDays(-$savedays[$i]) -and $_.LastWriteTime -gt (get-date).AddDays(-$savedays[$i+1])} |
        # Exclude the most recent folder from the aforementioned period
        Select-Object -Skip 1
        ) 

}

# delete folders
foreach ($folder in $killlist) {
    # delete the folder including contents
    Remove-Item $folder.fullname –recurse
}
