I'm going to play more with the code you just posted, but I found an old post (by you actually

) that used code.text in the replace.

So I am having success with the below code currently.
The below will prompt for the new File and replace the FilePath and FileName Separately. It's pretty 'quick', replacing about 70 links in a few seconds.
Code:
Sub ChangeFileLinks()
Dim f As Object
Dim i, x, fieldCount As Long
Dim OldPath, OldFile As String
Dim NewPath, NewFile As String
Set f = Application.FileDialog(3)
f.AllowMultiSelect = False
If f.Show Then
For i = 1 To f.SelectedItems.Count
'Get the File Path Only
NewPath = f.InitialFileName
NewPath = Replace(NewPath, "\", "\\")
MsgBox "The New File Path is: " & NewPath
'Get the FileName only. Uses Public FileName Function Below
MsgBox "The FileName Only is: " & Filename(f.SelectedItems(i))
NewFile = Filename(f.SelectedItems(i))
Next
End If
With ActiveDocument
fieldCount = .Fields.Count
For x = 1 To fieldCount
With .Fields(x)
'Debug.Print .Type
If .Type = 56 Then
'Get The Existing FilePath and File Name from the Link Sources
OldPath = .LinkFormat.SourcePath & "\"
OldPath = Replace(OldPath, "\", "\\")
'MsgBox "The Existing FilePath is: " & OldPath
OldFile = .LinkFormat.SourceName
'MsgBox "The Existing File Name is: " & .LinkFormat.SourceName
'Replace the FilePath
' Replace the link to the external file
.Code.Text = Replace(.Code.Text, OldPath, NewPath)
'.LinkFormat.SourceFullName = NewPath
'Replace the FileName
'.LinkFormat.SourceName = NewFile
.Code.Text = Replace(.Code.Text, OldFile, NewFile)
.Update
End If
End With
Next x
End With
End Sub
