I have several files in  a folder with one line in each of them. I want each lines put into one file appended after each other. Then I want to move the original file(s) to an archive folder. I am using VB.NET 2003. Do you have some code examples how to accomplish this? Thank you.

It might look something like...
Public Class Form1
 

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

        Dim sb As New System.Text.StringBuilder

        Dim outputFile As String = "c:\output.txt"

        Dim sourceFolder As String = "c:\data"

        Dim archiveFolder As String = "c:\archive"

        For Each file As System.IO.FileInfo In New System.IO.DirectoryInfo(sourceFolder).GetFiles("*.txt")

            sb.Append(ReadEntireFile(file.FullName))

            file.MoveTo(System.IO.Path.Combine(archiveFolder, file.Name))

        Next

        Dim sw As New System.IO.StreamWriter(outputFile)

        sw.Write(sb.ToString)

        sw.Close()

    End Sub
 

    Private Function ReadEntireFile(ByVal filename As String)

        Dim sr As New System.IO.StreamReader(filename)

        Dim entireFile As String = sr.ReadToEnd

        sr.Close()

        Return entireFile

    End Function
 

End Class

I wish I could make this stuff fluent for me like it seems for you. I guess I just keep at it. Seeing it makes it pretty clear.Thanks again for your assistance.
