Ce script créé par mes soins permet de supprimer tous les fichiers de log d'un dossier qui n'ont pas été modifiés depuis 30 jours.

Fonctionnalités :

• Supprime des utilisateurs (informations stockées dans un fichier csv) en masse d'un ou de plusieurs groupes AD
• Création d'un fichier de logs horodatés (Purge-Folder)
• Exporter les données dans un fichier .csv
• Exporter les données dans un rapport HTML

Utilisation :

• Compléter les variables suivantes dans le script :
  • $SourceFolder = "D:\Scripts\Purge-Folder\Logs" (Chemin d'accès aux fichiers de logs à purger)
  • $ConditionFiles = $AllFiles | Where-Object { ($_.LastWriteTime -lt (Get-Date).AddDays(-30)) -and ($_.Name -like "Test*") -and ($_.Extension -eq ".txt") } (Définir le nombre de jours, le nom et l'extension des fichiers à purger)
