I need to un-check 'prefered width' on table properties in hundreds of documents in the same folder. I'm a novice at Macros but made one I will share, It does not work and I need help finding out why. Any feedback is greatly appreciated.

Sub UpdateDocuments()
Application.ScreenUpdating = False
Dim strFolder As String, strFile As String, wdDoc As Document
strFolder = GetFolder


If strFolder = "" Then Exit Sub
strFile = Dir(strFolder & "\*.docx", vbNormal)
While strFile <> ""
Set wdDoc = Documents.Open(FileName:=strFolder & "\" & strFile, AddToRecentFiles:=False, Visible:=False)
With wdDoc
Dim pT As Word.Table
For Each pT In ActiveDocument.Tables
pT.PreferredWidth = Unchecked
Next

.Close SaveChanges:=True
End With
strFile = Dir()
Wend
Set wdDoc = Nothing
Application.ScreenUpdating = True
End Sub
Function GetFolder() As String
Dim oFolder As Object
GetFolder = ""
Set oFolder = CreateObject("Shell.Application").BrowseForFolder( 0, "Choose a folder", 0)
If (Not oFolder Is Nothing) Then GetFolder = oFolder.Items.Item.path
Set oFolder = Nothing
End Function

Any amendments would be greatly appreciated.

Thank you.

Preferred width is a cell property, so you need to apply it to the cells of the table, as below. I have not checked the rest of your code.
