Cannot create a file when that file already exists when using Directory.Move

Question

I am trying to move the directory from one location to another location on the same drive. I am getting \"Cannot create a file when that file already exists

Answer 1

As per MSDN,

This method throws an IOException if, for example, you try to move c:\mydir to c:\public, and c:\public already exists.

But, in your method, you are creating the destination directory before you move.

So, you need to change your method from

if (Directory.Exists(destinationdirectory))
{
  Directory.Move(sourcedirectory, destinationdirectory);
}
else
{
  Directory.CreateDirectory(destinationdirectory);
  Directory.Move(sourcedirectory, destinationdirectory);
}

to

if (Directory.Exists(destinationdirectory))
{
  //delete or rename
}
Directory.Move(sourcedirectory, destinationdirectory);
