Delete Files Based On File Age

Ever wanted to delete every file over a certain age? Maybe for pesky log files that are ballooning the storage on your server?

The below script will delete all files in a specified folder that is older than the current date. Modify as necessary to change the age of files you want. Set up a Windows task to run as necessary. 

$folder = "C:\Path\To\Folder"
$date = Get-Date -format "MM/dd/yyyy" | out-string
$files = Get-childitem -path $folder | where {$_.LastWriteTime -lt $date}
Remove-item $files.FullName

Enable Inheritance Without Taking Ownership

Having NTFS permissions that are messed up is a HUGE headache. Fixing them means trying to trick NTFS into letting you do what you need to, and sometimes it just won’t let you. Below is my nuclear option that will, at least, get you back where you can make the necessary changes to get what you need set.

Download the NTFSSecurity powershell module, unblock the zip file, then extract it to C:\Windows\System32\WindowsPowerShell\v1.0\Modules

Make sure that the top level folder has the permissions you want to inherit. Make sure you have permissions on this top level folder.

Run Powershell as admin. 

Run the following commands in the folder you want to propagate inheritance down from: 

import-module ntfssecurity
enable-privileges
get-childitem -recurse | Enable-NTFSAccessInheritance

Increase Max Concurrent Shells

When running a remote Powershell command, you might get the following error. To resolve, you’ll need to either figure out why it’s using so many concurrent shells, if that’s not what you’re expecting, or increase the maximum number of concurrent shells. 

Connecting to remote server $Server failed with the following error message : The WS-Management service cannot process the request. This user has exceeded the maximum number of concurrent shells allowed for this plugin. 
Close at least one open shell or raise the plugin quota for this user. For more information, see the about_Remote_Troubleshooting Help topic.

To increase the maximum number of concurrent shells (defaults to 25) use the following powershell commands:

 winrm get winrm/config/winrs

This will get you the details of the current configuration. Look for “MaxProcessesPerShell.”

Use the following to set the max. 

 winrm set winrm/config/winrs '@{MaxProcessesPerShell="<WhateverNumberYouWant"}'
