rename file in c#

meeeeeeeeeep

i use:
fiFileInfo.CopyTo(Path.ChangeExtension(fiFileInfo. FullName + fiFileInfo.Extension, ".enc"), false);
to rename a file (eg: crap.ppt -> crap.ppt.enc).

if the file is really big (400mb), this take 6-7 minutes. is there a better way to rename files?

regards

try

fiFileInfo.MoveTo( Path.ChangeExtension(fiFileInfo.FullName + fiFileInfo.Extension, ".enc") )

It is better to use method
Path.ChangeExtension(string path, string extension);

namespace rhozetApplication3

{

    public partial class Form1 : Form

    {

        public Form1()

        {

            InitializeComponent();

        }
 
        private int File_Delete(string Filepath)

        {

            FileInfo fi = new FileInfo(Filepath);
 
            if (fi.Exists)

            {

                fi.Delete();

            }

            return 1;

        }
 
        private int File_rename(string FilepathOld, string FilepathNew)

        {

            FileInfo fi = new FileInfo(FilepathOld);
 
            if (fi.Exists)

            {

                fi.MoveTo(FilepathNew);
 
            }

            return 1;

        }
 
        private void button1_Click(object sender, EventArgs e)
 
        {
 
            FileInfo fi = new FileInfo("C:\\dateiname.txt");
 
            if (fi.Exists)

            {

                fi.MoveTo("C:\\dateiname.mpg");

                textBox1.Text = "           Succesfull!    ";

            }

            else

            {

                textBox1.Text = "           Failed!    ";

            }

        }

    }}

\\ a button and a text box is requiert to run it

have fun

TIP: When you are writing your question, there is a button on the tool bar that wraps the [code] tags around your copy/pasted code. It helps a bunch. Its the button with a '#' on it. More on tags. They're cool. Check'em out.
