Sitecore PowerShell script to list unused media items with a prompt for folder location

I was recently asked to produce a report of all the unused media items in Sitecore for a specific Region folder and if you have the PowerShell extensions installed then there is a great one in there called “Media items not used by content items”.

Unfortunately this takes a very long time to run if you have a huge amount of media items in your library and didn’t allow the end user to specify a folder which lead me to extend it a little bit.

By extending the original script by Michael West and adding a Read-Variable prompt it gives the end user more flexibility:

$result = Read-Variable -Parameters `
 @{ Name = "item"; Title="Analyse subitems of"; Tooltip="Folder you want to analyse."; Root="/sitecore/media library/"} `
 -Title "Find all media items that are not in use" -Width 600 -Height 200 `
 -OkButtonName "Proceed" -CancelButtonName "Abort"

Which displays like so:

sitecore powershell read item prompt

You then get a brilliant list view of the results once the script has finished which allows the end user to export as CSV, Excel etc
