Powershell delete folder files based on date range criteria

Below command, delete files older than 30 days

Get-ChildItem –Path "C:\path\to\folder" -Recurse | Where-Object {($_.LastWriteTime -lt (Get-Date).AddDays(-30))} | Remove-Item

But how to add filters, that dont delete files if

date is 1st of each month or
date is 15th of each month or
date is 30
also ignore files with name '%weekly%'

Since you only want to remove files, you should use the -File switch on the Get-ChildItem. In order not to keep calculating the reference date 30 days ago, I like to define that in a variable $refDate first. Also, you should use the date, as of midnight by setting the time part to 00:00:00. That is where property Date comes in.

$refDate = (Get-Date).AddDays(-30).Date  # set it to midnight
Get-ChildItem -Path "C:\path\to\folder" -File -Recurse | 
    Where-Object { ($_.LastWriteTime -lt $refDate) -and
                   ($_.BaseName -notlike '*%weekly%*') -and
                   (1,15,30 -notcontains $_.LastWriteTime.Day)} | 
    Remove-Item -WhatIf

P.S. I have added the -WhatIf switch, so you can see what would happen first. If you are satisfied with the messages in the console, remove this switch to actually start deleting files

You can go for powershell script like below:

$FolderName = "c:\dev\test"
foreach($file in (GEt-childitem -Path $FolderName -Recurse | Where-Object {($_.LastWriteTime -lt (Get-Date).AddDays(-30))} ))
{
 if (($file.lastwritetime.Date.Day  -in 1,15,30 ) -or ($file -like '*weekly*'))
 {
   continue
 }
 
 Remove-Item -Path $file.FullName
}
