Steps to reproduce the problem:
Since 2008 this feature miss, you can't speak about security... others browser do this (firefox put downloaded file in temp file and when firefox close the downloaded file are removed) you can read here: http://webapps.stackexchange.com/questions/11973/opening-files-directly-in-google-chrome

What is the expected behavior?
when click on link open file instead download it,,,,or download it but no put it on Download files (directly delete) or put it on /temp files and when chrome close remove all temp file I don't know 

What went wrong?
Actually when we open file directly on selecting "open this file directly and save it" ...the files's open directly BUT the problem is /Download folder always add opened file... please FIX this ONCE !!!!
