Hi,

I merged rtf files using the code below in vb.net desktop application.

After it has merged, it does not retain its original format. i.e. the line space is widened.

Try
    Dim allRTFDocument As String() = System.IO.Directory.GetFiles(Application.StartupPath & ("\Data2\" & txtLangCode.Text & ""), "*.rtf")
    Dim characters As String() = New String() {"A", "B", "CH", "D", "E", "Ẹ", "F", "G", "GB", "GH", "GW", "H", _
                                               "I", "Ị", "J", "K", "KP", "KW", "L", "M", "N", "NW", "NY", "Ṇ", _
                                               "O", "Ọ", "P", "S", "Ṣ", "T", "U", "Ụ", "V", "W", "Y", "Z", "Ẓ"}
    Dim files As List(Of String) = New List(Of String)()

    For Each character As String In characters
        Dim chars As String = character.ToLower()
        Dim matchFiles As String() = Array.FindAll(allRTFDocument, Function(c) System.IO.Path.GetFileName(c).ToLower().StartsWith(chars))
        For i As Integer = 0 To matchFiles.Length - 1
            files.Add(matchFiles(i))
        Next
    Next

    Merge(files.ToArray(), My.Computer.FileSystem.SpecialDirectories.MyDocuments & "\Dictionary.docx", True, "")
Catch ex As Exception
    MsgBox("No data to export", MsgBoxStyle.Information)
End Try

In this case, what do I do?

Hi dnnyobi,

Refer Below Code

    string[] allRTFDocument = Directory.GetFiles(@"C:\\Files", "*.rtf");
    Merge(allRTFDocument, @"C:\\Final.rtf", true);
}

public static void Merge(string[] filesToMerge, string outputFilename, bool insertPageBreaks)
