I would use FileInfo.CopyTo(string). Here is the MSDN link: http://msdn.microsoft.com/en-us/library/f0e105zt.aspx

Basically

string sourcePath = //Whatever you want to copy
string destPath = //Where you want to copy it to

FileInfo fInfo = new FileInfo(sourcePath);
fInfo.CopyTo(destPath)

I've never actually done that before though. If you want to move files around, I strongly advise you to use shell scripting (bash under linux or batch under Windows). There may be some exceptions you must handle under C# (e.g. what happens if you try to access a file in C# that Windows doesn't think you are allowed to? it throws a security exception at you that you must handle lest your program crash).

Hope that helps.

In general avoid using batch files in Windows. The reason is that you can't easily capture any errors inside your C# program.

Instead, use the corresponding C# class (or Win32 api) to get the job done.

For file copying, see the File.Copy class in msdn.

try
{
  File.Copy( sourceFileName, destFileName );
}
catch( Exception e )
{
  // report error
}
