Hi,

I want to change a single word in all files in a specific folder, but I don't want the modified date changed.

Is it possible.

With this script it changes the word but also changes the modified date.

$Path = "\\Archive\test\Archive\*.xml"
Get-ChildItem -Path "$Path" |
foreach-Object{
        if((Get-Content $_) -match 'http://Archive/test/VPCflow/Forms/template.xsn'){
                "$_"
                 (Get-Content $_) |
                 Foreach-Object {$_ -replace 'http://Archive/test/VPCflow/Forms/template.xsn', 'http://Archive/test/Archive/Forms/template.xsn'} |
                 Set-Content $_
         }
}

Kind of an odd request.
When you modify a file, the modified time is always updated, however it is possible to set this property.  First you have to store the original time, and after the file modification, set the property to this time.
$Path = "\\Archive\test\Archive\*.xml"
Get-ChildItem -Path "$Path" | ForEach-Object {
    if ((Get-Content $_) -match 'http://Archive/test/VPCflow/Forms/template.xsn')
    {
        "$_"
        $modtime = $_.LastWriteTime
        (Get-Content $_) | 
        Foreach-Object { $_ -replace 'http://Archive/test/VPCflow/Forms/template.xsn', 'http://Archive/test/Archive/Forms/template.xsn' } |
        Set-Content $_
        $_.LastWriteTime = $modtime
    }
}
