Get the starting folder
Set fsFolder = fs.GetFolder(FolderPath)
Iterate thru every file in the folder
For Each fsFile In fsFolder.Files
     Compare the current file extension with the list of valid target files
    If InStr(1, ValidFiles, Right(fsFile.Name, 3), vbTextCompare) > 0 Then
     DocCount = DocCount + 1
     Open the file to read its content
        Set fsText = fsFile.OpenAsTextStream
            FileText = fsText.ReadAll
             Apply the regex search and get the count of matches found
            MatchCount = Regex.Execute(FileText).Count
            MatchedCount = MatchedCount + MatchCount
            If  MatchCount > 0 Then
                DocMatchCount = DocMatchCount + 1
                 Apply another regex to get the html documents title
                Set FileTitleMatch = GetTitle.Execute(FileText)
                If FileTitleMatch.Count > 0 Then
                     Strip the title tags
                    FileTitle = Trim(replace(Mid(FileTitleMatch.Item(0),8),"</title>","",1,1,1))
