I currently use the following macro to scrub, password protect, and save Word files. Each filename contains the text "(IU)". I would like to amend the macro so that it will also replace "(IU)" with "(CR)" in the filename, before saving it.

Sub ThirdPartyDocsScrubLockSaveClose()

ActiveDocument.RemoveDocumentInformation (wdRDIDocumentProperties)
ActiveDocument.RemoveDocumentInformation (wdRDIDocumentServerProperties)
ActiveDocument.RemoveDocumentInformation (wdRDIContentType)
ActiveDocument.Protect Password:="12345", NoReset:=False, Type:= _
wdAllowOnlyReading, UseIRM:=False, EnforceStyleLock:=True
CommandBars("Restrict Editing").Visible = False
ActiveDocument.Save
ActiveDocument.Close
End Sub
