下面的代码将删除文件夹中超过15天的文件。

$Path = 'C:\Temp'
$Daysback = "-15"
$CurrentDate = Get-Date
$DatetoDelete = $CurrentDate.AddDays($Daysback)
Get-ChildItem $Path -Recurse  | Where-Object { $_.LastWriteTime -lt $DatetoDelete } | Remove-Item

试试这个:

dir C:\PURGE -recurse | 
where { ((get-date)-$_.creationTime).days -gt 15 } | 
remove-item -force

简单地(PowerShell V5)

Get-ChildItem "C:\temp" -Recurse -File | Where CreationTime -lt  (Get-Date).AddDays(-15)  | Remove-Item -Force

如果你在Windows 10系统上使用上述示例有问题，请尝试将. creationtime替换为. lastwritetime。这对我很管用。

dir C:\locationOfFiles -ErrorAction SilentlyContinue | Where { ((Get-Date)-$_.LastWriteTime).days -gt 15 } | Remove-Item -Force

Esperento57脚本在较旧的PowerShell版本中无法运行。这个例子是:

Get-ChildItem -Path "C:\temp" -Recurse -force -ErrorAction SilentlyContinue | where {($_.LastwriteTime -lt  (Get-Date).AddDays(-15) ) -and (! $_.PSIsContainer)} | select name| Remove-Item -Verbose -Force -Recurse -ErrorAction SilentlyContinue

另一种选择(15。自动输入[timespan]):

ls -file | where { (get-date) - $_.creationtime -gt 15. } | Remove-Item -Verbose
