I found a way to do this, but you need to use User32.dll sendmessage() function, after you press button\link and you have your download dialog i use sendmessage to send key's i send:
1- (F6) it will select the download dialog.
2-(Tab) -it will select the first option Save.
3- (Enter) will press Save button that will save file to deafault derectory
4- For 100% i check in registry the defeaul folder of IE and easy find my file and copy it to directory that i need.
Why i use sendmessage and not sendKey?
Answer: sendmessage will still press on buttons even if windown is lock no need UI.

Browser security will not allow this.
