PowerShell Clean up temporary folders

When disk space changes to an hour, we can resolve it by cleaning up the temporary folder. We use PowerShell to write a program that can clean up files that were 30 days old in the Windows Temp folder.

Copy Code code as follows:

$cutoff = (get-date)-(new-timespan-days 30)
$before = (get-childitem $env: Temp | Measure-object length-sum). Sum

Get-childitem $env: Temp |
Where-object {$_. Length-ne $null} |
Where-object {$_. Lastwritetime-lt $cutoff} |
Remove-item-force-erroraction silentlycontinue-recurse-whatif
$after = (get-childitem $env: Temp | Measure-object length-sum). Sum
$freed = $before-$after
' Cleanup freed {0:0.0} MB. '-F ($freed/1MB)
