    I need to delete backed up files older than 10 days and then remove the now empty folder they were in. I currently have everything working accept the part where it determines if the file has been backed up using the A attribute on the file.

    any suggestions for this part? I'm stumped

    I've uploaded what I have so far that works.

    Try this:

    $dir = "C:\Temp"
    $tenDaysAgo = (Get-Date).AddDays(-10)

    if (Test-Path -Path $dir)
    {
        # I'm guessing you need to check the attribute here?
        Get-ChildItem -Path $dir -Filter "*.gsa" -Recurse | Where-Object {
            ($_.LastWriteTime -le $tenDaysAgo) -and
            (($_.Attributes -band [System.IO.FileAttributes]::Archive) -ne [System.IO.FileAttributes]::Archive)
        } | ForEach-Object {
            Write-Host "Deleting " -NoNewLine
            Write-Host $_.FullName -ForegroundColor Blue
            Remove-Item -Path $_.FullName
        }
    }
    else
    {
        Write-Host "$dir does not exist." -ForegroundColor Red
    }

    Get-ChildItem -Path $dir | Where-Object { $_.PsIsContainer } | ForEach-Object {
        if (($_.GetFiles().Length -eq 0) -and ($_.GetDirectories().Length -eq 0)) {
            Remove-Item -Path $_.FullName -Verbose
        }
    }

    Thanx for your help I think you are on the right track however when I run your adjusted version it still only delete's files older than 10 days even if they have not been archived. For my need it needs to skip files that have not been backed up even if they are older than 10 days.

    For testing the files I'm using are 10 days old and all seem to have a file attribute of AI, while on the server where this will be run the files will be over 10 days old and if they have been backed up will have a file attribute of A.

    General purpose is to clean up some groove backup files and folders as longs as those files have been backed up to tape.

    Thank you for your help so far.

    Yes, I made a mistake:

    (($_.Attributes -band [System.IO.FileAttributes]::Archive) -ne 0)

    ...should be:

    (($_.Attributes -band [System.IO.FileAttributes]::Archive) -ne [System.IO.FileAttributes]::Archive)

    I edited by original post, try that.

    Hmm getting more interesting but this version ends up not deleting anything, even the files that are older than 10 days that I have changed the file attribute to A.

    I tried adjusting the attribute field you used to Archived or just A and that seems invalid and then it just nukes them by date instead.
    I verified it kept the old date modified time on the files after changing the attribute to them to A.

    I knew this part would suck, the part you adjusted do I need to add some type of get attribute part like I did with the $dir and $date?

    Try it like this:

    $dir = "C:\Temp" $tenDaysAgo = (Get-Date).AddDays(-10) if (Test-Path -Path $dir) { # I'm guessing you need to check the attribute here? Get-ChildItem -Path $dir -Filter "*.gsa" -Recurse | Where-Object { $_.LastWriteTime -le $tenDaysAgo } | Where-Object { $_.Attributes -band [System.IO.FileAttributes]::Archive } | ForEach-Object { Write-Host "Deleting " -NoNewLine Write-Host $_.FullName -ForegroundColor Blue Remove-Item -Path $_.FullName } } else { Write-Host "$dir does not exist." -ForegroundColor Red } Get-ChildItem -Path $dir | Where-Object { $_.PsIsContainer } | ForEach-Object { if (($_.GetFiles().Length -eq 0) -and ($_.GetDirectories().Length -eq 0)) { Remove-Item -Path $_.FullName -Verbose } }

    So, you want to delete files that:

    - Are 10 days old or older AND have been archived (have the 'A' attribute)

    Right? If so:

    $dir = "C:\Temp"
    $tenDaysAgo = (Get-Date).AddDays(-10)

    if (Test-Path -Path $dir)
    {
        Get-ChildItem -Path $dir -Filter "*.gsa" -Recurse | Where-Object {
            ($_.LastWriteTime -le $tenDaysAgo) -and
            (($_.Attributes -band [System.IO.FileAttributes]::Archive) -eq [System.IO.FileAttributes]::Archive)
        } | ForEach-Object {
            Write-Host "Deleting " -NoNewLine
            Write-Host $_.FullName -ForegroundColor Blue
            Remove-Item -Path $_.FullName
        }
    }
    else
    {
        Write-Host "$dir does not exist." -ForegroundColor Red
    }

    Get-ChildItem -Path $dir | Where-Object { $_.PsIsContainer } | ForEach-Object {
        if (($_.GetFiles().Length -eq 0) -and ($_.GetDirectories().Length -eq 0)) {
            Remove-Item -Path $_.FullName -Verbose
        }
    }

        } | ForEach-Object {
            Write-Host "Deleting " -NoNewLine
            Write-Host $_.FullName -ForegroundColor Blue

        }

            Remove-Item -Path $_.FullName -Verbose
        }
    }

    This one deleted files with the A attribute but also with the AI attribute.
