Hi mwilliams71
Just an idea, in your case first I will download the stream, and by the Microsoft.PowerShell.Utility I'll compare both files.

I want to automate this by using PowerShell and if any code is different in the multiple directories, PowerShell should copy what files have changed to the Library.
Hi mwilliams71
Here it is an example assuming only one site, please adapt and test because you want to compare a stream
Add-PSSnapin Microsoft.SharePoint.PowerShell -ErrorAction SilentlyContinue #Variables for Processing $SourceWebURL = "https://Your-Source-Web-URL" $SourceLibrary ="Team Docs" $TargetLibrary = "Shared Documents" $ColumnToCompare="Your Compare Column Name" $Web = Get-SPWeb $SourceWebURL $ListOne = $web.lists[$SourceLibrary] $ListTwo = $web.lists[$TargetLibrary] $ListOneValues = @() $ListTwoValues = @() $ListOne.Items| foreach { $ListOneValues+= $_[$ColumnToCompare] } $ListTwo.Items | foreach { $ListTwoValues+= $_[$ColumnToCompare] } Compare-Object $ListOneValues $ListTwoValues- If the column "Modified" is different, what result will I get? and how will I store this into a variable?
This may work for initiating the copy file PowerShell script.- See link in first reply, have examples
