You should use physical paths. That is :

string fileName="file.txt";
string sourcePath = @"C:\inetpub\wwwroot\source";
string targetPath =  @"C:\inetpub\wwwroot\dest";   

string sourceFile = System.IO.Path.Combine(sourcePath, fileName);
string destFile = System.IO.Path.Combine(targetPath, fileName);

System.IO.File.Copy(sourceFile, destFile, true);

If you need to involve the website root (in this case, folders on the site root folder), it should be like this:

string fileName="file.txt";
string sourcePath = Server.MapPath("/source");
string targetPath =  Server.MapPath("/dest");   

string sourceFile = System.IO.Path.Combine(sourcePath, fileName);
string destFile = System.IO.Path.Combine(targetPath, fileName);

System.IO.File.Copy(sourceFile, destFile, true);
