Deleting old files using PowerShell scripts

Join us in this article to discover how to delete old files using PowerShell scripts that automatically remove files older than a specific creation date.

System administrators often need to clean up directories like temp folders, log files, swap drives, and more. Unfortunately, manual review and sorting can be time-consuming and error-prone.

In many cases, we need to delete files older than a certain age. This article provides a simple script you can run manually or integrate into a scheduled task that executes at regular intervals.

How to delete old files using PowerShell scripts?

The command structure is:

Get-ChildItem -Path "<PATH_TO_SCAN>" -Recurse | 
Where-Object CreationTime -LT (Get-Date).AddDays(-<DAYS>) | 
Remove-Item

Where:

• Get-ChildItem: Lists files and directories in a path.
• -Path "<PATH_TO_SCAN>": Defines the starting path for scanning.
• -Recurse: Scans recursively through all subfolders.
• |: Pipes output to the next command.
• Where-Object CreationTime -LT (Get-Date).AddDays(-<DAYS>): Filters files older than the specified number of days.
• Remove-Item: Deletes matching files.

Example: Delete files older than 7 days from C:\Drivers\lj368\:

Get-ChildItem -Path "C:\Drivers\lj368\" -Recurse | 
Where-Object CreationTime -LT (Get-Date).AddDays(-7) | 
Remove-Item

This deletes files directly, but you might prefer to list them first or export to a file for review.

Quick cleanup: Delete old files with PowerShell

If you just want to run it without the details, use this command:

Get-ChildItem -Path "<PATH_TO_SCAN>" -Recurse | 
Where-Object CreationTime -LT (Get-Date).AddDays(-<DAYS>) | 
Remove-Item

Replace:

• <PATH_TO_SCAN>: Your target folder path.
• <DAYS>: Number of days (numeric).

Run the one-liner and wait for completion.
