Here's your code.  Call this from your macro...

Make sure that you set the path properly, and if your text file has different extension than .TXT, change it in the following code:

 
Public Sub ManipFiles()
    Dim sPath As String
    Dim aFile
    Dim sFileTxt As String
    Dim InFile, OutFile
    Dim nLines As Integer
    
    sPath = "C:\TEMP\"
    
    aFile = Dir(sPath & "*.TXT")
    While aFile <> ""
        InFile = sPath & aFile
        OutFile = sPath & "TMP.TXT"
        
        Open InFile For Input As #1
        Open OutFile For Output As #2
        
        nLines = 0
        Print #2, "Title"
        While Not EOF(1)
            nLines = nLines + 1
            Input #1, sFileTxt
            If nLines >= 5 Then
                Print #2, sFileTxt
            End If
        Wend
        Close #1
        Close #2
        Kill InFile
        Name OutFile As InFile
        
        aFile = Dir
    Wend
End Sub

You may also add a line at the end to know when the code has finished to run, because if you run that over 318 files, depending on their size, it might take a while.

I'm not sure why this is in the Excel zone.  Do you plan to run the code from Excel?  What type of files are these (comma-delimited, fixed-width, other)?

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

I was going to post some code using the FileSystemObject, but the code above should do the job.

sorry, i gave the solution in the language that i know.   I could have done it in VB Script too with FileSystemObject... but i've no clue how to do this in Powershell.  I've never done that before so if you know that Helen, go ahead...

There's a stack of ways you can do it. But here's one, pretty basic. Skips the first 4 lines of the file and replaces the 5th line with the text you want at the top of the file. Other ways could be to import the file, remove the first 5, insert a new line, etc.
GCI c:\path\textfiles -Filter *.txt | % {
   $arrTemp = GC $_.fullname | Select -Skip 4
   $arrTemp[0] = "Title"
   $arrTemp | Set-Content $_.Fullname
}
