Hi Guys

Im new to PS scripting and currenlty building my knowledge as i go . A few work mates and my self are currenlty working on a little task to delete any files thats older than 7 days using an application called JAMS(Job access managemnet system).

whats required : i need to write a PS script to delete files older than X Daysm in this case any files older than 7days

PS script i have drafted is below but fails with the following message :

$TargetFolder = "<<Path>>"
Get-ChildItem $TargetFolder -recurse -include *.pdf | Where-Object $.CreationTime -lt ($(Get-Date).AddDays(-7)) | Remove-Item $.FullName -force

Fails with the following
------------------------------------
Error: Where-Object : Cannot bind argument to parameter ‘FilterScript’ because it is n
Error: ull.
Error: At C:\ProgramData\JAMS\Temp\xPression_Task_OBD_Print_Powershell_0000CC9A.ps1:8

Use {} around your Where-Object filter like this:

Where-Object {$.CreationTime -lt ($(Get-Date).AddDays(-7))}

Cheers coderaven ,

have added {} but failed with the same error, have copied the error below.
Get-ChildItem $TargetFolder -recurse -include *.pdf | Where-Object {$.CreationTime -lt ($(Get-Date).AddDays(-7))} | Remove-Item $.FullName -force


Error: Remove-Item : Cannot bind argument to parameter ‘Path’ because it is null.

You can’t use $ outside of the Where filter script. Remove $_.FullName entirely. Let it pick up the path and file name from the pipeline.
