Hello Michel;

Thanks a lot for your reply.

I´m a little confuse.

Could you give me hand to apply your recomendation to my script?

My script
Using sr As StreamReader = txtfile.OpenText
File.AppendAllText(Path.Combine(topDir.FullName, curFilename), sr.ReadToEnd, Encoding.Default)
End Using

Your script
Using loFileStream As System.IO.FileStream = New FileStream(lcFile, FileMode.Create)
loStreamWriter = New StreamWriter(loFileStream, cEncoding)
loStreamWriter.Write(cString)
loStreamWriter.Close()
End Using

Thanks a lot
