how to delete into recycler?
 

DELETE and RMDir deletes immediately. but how do i delete into recycler?

There is a page in the wiki that might help you:

http://nsis.sourceforge.net/Send_to_Recycle_Bin

I believe the code pengyou linked to was broken so I rewrote it :) . You can find the old version here

thank you both, is working well. background is that sabdboxie do not allow 16bit programs and i need a replacement for deltree so i wrote deltreew with recycler option.
there already exist a solution http://www.novell.com/communities/node/7064/deltreew
but that is too much code around.
