PowerShell - Find Wild Card Directory With Hidden Attribute Within Past X Days

Posted on 2014-01-16

Last Modified: 2014-01-27
- I need to create a PowerShell that will look for directories called "*.view".

- These directories have a Hidden attribute, so I only want to find those directories that are hidden.

- I'd like to look for directories that are older than X amount of days.

- For safety reasons, I'd like two options for output and I'll just comment out the one I don't need to use at any given time.

- First options is to create an output file to the desktop, so i can review it and make sure it's correct.

- The second option would be to actually remove the directories. Again, I'll just comment out the one I don't want to use when I first run the script.

$Now = Get-Date
$Days = "7"
$TargetFolder = "C:\Temp\"
#----- define LastWriteTime parameter based on $Days ---#
$LastWrite = $Now.AddDays(-$Days)

$folders = Get-Childitem $TargetFolder -Include *.view -filter *. -Attributes h  -Recurse | Where {$_.LastWriteTime -le "$LastWrite"}

# above $_.Lastwritetime can be replaced with $_.creationtime  to actually look for old days based on lastwritetime or creationtime.

foreach ($folder in $folders)
          {
          if ($folder-ne $NULL)
              {

#              write-host "Deleting folder $folder" -ForegroundColor "DarkRed"

              "Deleting folder $folder" | add-content c:\result.txt

#              Remove-Item $folder.FullName | out-null
              }
          else
              {
#              Write-Host "No more folders to delete!" -foregroundcolor "Green"

            "No more folders to delete!" | add-content c:\result.txt
              }
          }

Hello Wizard,

I'm getting the following error message:

PS C:\Users\5sun5\Desktop> C:\Users\5sun5\Desktop\boo.ps1
Get-ChildItem : A parameter cannot be found that matches parameter name 'Attributes'.
At C:\Users\5sun5\Desktop\boo.ps1:7 char:78

Use the following instead

$folders = Get-Childitem $TargetFolder -Include *.view -filter *. -Recurse | where { $_.attributes -match "hidden"} | Where {$_.LastWriteTime -le "$LastWrite"}

Almost. Hidden folders and files are not shown by Get-ChildItem. And we really should restrict the search to folders (the above will also find files).
Further, first parsing the complete tree, and then act on the result is usually ineffective, so I recommend to use a pipe:
$Test= $true
$old = (get-date).AddDays(-7)     # 7 days back
Get-ChildItem -recursive -Filter *.view -Force | 
  ? { $_.Mode -like 'd??h' } |
  ? { $_.LastWriteTime -le $old } |
  % {
    if ($Test)
    {
      Out-File C:\Results.txt "Deleting folder $($_.FullName)" 
    } else  {
        Write-Host write-host "Deleting folder $($_.FullName)" -ForegroundColor "DarkRed"
        Remove-Item -recursive -force $_
   }

I took the liberty to define "to the desktop" as C:\ ;-).
Change $Test to $false to delete the folders.

Did you test that script? It doesn't work.
And, btw, "Wizard" is a rank, not a name. The name is visible at the right of "by: ", and hence is "Qlemo" (for me) and "Raheman Mohammed Abdul" for the other Expert ;-).

I have to insist in knowing why you accepted a non-working suggestion.

Qlemo, it 100% works. Why would you question my integrity on a message board? I have nothing to gain and all to lose if I were being dishonest.

Because this does not show anything for me:
md x.view
attrib +h x.view
Get-Childitem -Include *.view -filter *. -Recurse
