Hi guys,

I have to rename over 2000 files.

I get the files by using:

$List = Get-ChildItem -Filter *2015*

Then i only want the first 8 characters and i do:

$List = ForEach-Object {$a.Substring(0,13)}

The i add some text

$b = $a | Foreach-Object{ $_ + '_bw' }
$c = $b | Foreach-Object{ $_ + '.pdf' }

But i only receive the last file in the c$ could somebody help me to change all the filenames put it in a string and then rename the files on fileserver

You should start with learning the basics of Powershell. Here are some good sources: Beginner Sites and Tutorials
Your task could be accomplished like this:

Get-ChildItem -Path C:\sample\* -Filter *2015* | 
    ForEach-Object -Process {
        $newName = $($_.BaseName.substring(0,8)) + '_bw' + $($_.Extension)
        Rename-Item -Path $_.FullName -NewName $newName
    }

Of course you should change the starting path to your needs
