Copy Multi Folders using Robocopy for "Infinite Folders"

Intro dulu ya ....
gw lagi coding php, pake php designer 8. trus gw coba-coba toolsnya. ada export, eh pas gw coba, kok ga beres2 copynya?? trus gw cancel. pas gw liat, eh ternyata ngebuat folder yg banyak bgt.
gw coba cek pake software2, ada sekitar 475 folders (dibaca: tak terbatas a.k. infinity / infinite).
foldernya ampe ga bisa dibuka.
trus gw googling2.
- pake cmd , pake cara buat remove autorun.inf nya SMADAV seperti rmdir, rd, del, erase.
- install winUtilities, Unlocker, pake power shell, dsb.
- trus gw coba robocopy. pake cmd jg. setelah menggila lama , akhirnya nemu juga caranya. yaitu
robocopy [source] [dest] /purge /s /mov
contoh :  robocopy c:\hapus\a\ c:\delete\a\ /purge /s /mov

beres deh...

So, ini kesimpulannya :
Pakai Robocopy (using cmd)
command : 
robocopy [source] [dest] /purge /s /mov
contoh :  robocopy c:\hapus\a\ c:\delete\a\ /purge /s /mov

using Entity Framework or EF to copy an Object.

using Entity Framework or EF to copy an Object.
This can be used to avoid Error : PK cannot be modified :
"The property 'MyPrimaryKey' is part of the object's key information and cannot be modified. "
we can use this query :

var item = _context.MyTableName.First(z => z.Name == "Ardi");
var newItem = (MyTableName)_context.Entry(item).GetDatabaseValues().ToObject();
newItem.MyPrimaryKey = "Generated_" + DateTime.Now.ToString();
_context.SaveChanges();
