How to delete folders that were not created in the current year?

  • 772

I am making a Script that has to delete all the files in a directory that do not match the creation date with the year in which it is executed, that is, if I execute it in 2017 it deletes everything that has not been created that year.

I have managed to get the year, but I don't know how to delete the files:

$yearOs = Get-Date -Format yyyy
$yearItems = Get-ChildItem E:\Backup\ | get-date -Format yyyy

foreach ($i in $yearItems) {
  if ($i -ne $yearOs) {
  echo $i # esto da cualquier fecha que no sea el año en el que se ejecuta
  }
 }

I have also thought about using the command forfilesbut I already told you that in PS I am a little green.

    This script will suffice

    Get-ChildItem <ruta> |
    ? { $_.CreationTime.Year -ne (Get-Date).Year } |
    ForEach { Remove-Item -Recurse -Force $_.FullName }

    Note: Replace with the correct path to your directory, for example:E:\Backup\

    Explanation:

    Get-ChildItem <ruta> |

    This line gets the child directories of <ruta>.

    ? { $_.CreationTime.Year -ne (Get-Date).Year } |

    This line makes a filter (where) and returns only directories that do not have the current year as modification date.

    ForEach { Remove-Item -Recurse -Force $_.FullName }

    This line loops through each of the directories from the previous step and recursively removes them (including all their subdirectories).
