Script to convert Word 97, 03, & 07 doc to Word 2010 docx format

I'm pretty new to powershell I found a ps script that will convert old Microsoft Word 97, 2003, and 2007 documents from the extension .doc to the new Microsoft Word format extension .docx. I have over 100 old word documents from Users on our network.

Here's what I have:

[ref]$SaveFormat = “microsoft.office.interop.word.WdSaveFormat” -as [type] 

$word = New-Object -ComObject word.application 

$word.visible = $false 

$folderpath = “c:\Users\user\desktop\username_old_docs"

$fileType = “*doc” 

Get-ChildItem -path $folderpath -include $fileType | 

foreach-object ` 

{ 

$path = ($_.fullname).substring(0,($_.FullName).lastindexOf(“.”)) 

“Converting $path to $fileType …” 

$doc = $word.documents.open($_.fullname) 

$doc.saveas([ref] $path, [ref]$SaveFormat::wdFormatDocumentDefault) 

$doc.close() 

} 

$word.Quit() 

$word = $null 

[gc]::collect() 

[gc]::WaitForPendingFinalizers()

When I run the ps1 script I'm getting this:

cmdlet ForEach-Object at command pipeline position 2

Supply values for the following parameters:

Process[0]:

I feel that I might be missing the path for when the files are converted as to where they will get saved. Any help would be greatly appreciated.

Thanks,
