Rename Multiple Text Files

In a folder I have several text files (each text file is a customer statement)
I get the files from the computer dept named randomly, I need to rename each
File to its customer ID number, each ID consists of 15 characters (including the dash characters) and is found on the 3rd row of the file (3rd row , skip one character And count 15 characters ex : 0010-902514-422)

I found a code that renames the text files incrementally (1,2,3…..). I need to modify the code so that instead of renaming the files that way I rename them by their ID number (get the ID of each file while looping then rename It by that ID)
One more thing, can I get the ID then skip 44 characters and attach the following 14 characters to the ID (ex : 0010-902514-422- Lebanese Pound). ttached is a folder containing an excel file with the code and 2 statements

Sub RenFile()
Dim arrFiles As Variant
Dim intCounter As Integer
Dim datFile As Date
Dim strFile As String, strPath As String
strPath = ActiveWorkbook.Path
arrFiles = FileArray(strPath, "*.txt")
For intCounter = 1 To UBound(arrFiles)
strFile = arrFiles(intCounter)
Name strPath & strFile As strPath & intCounter & ".txt"
Next intCounter
End Sub

Private Function FileArray(strPath As String, strPattern As String)
Dim arrDatabase()
Dim intCounter As Integer.............................
