Drop functionality

You can download files from your NAS :)
You can see this files in application and if its simple file open this :)
But if it is file in not most popular format (e.g. *.kdbx - KeePass) you have problem :(
You need send this file via email and in Mail "open in" your favorit application.
This is little stupid.
In earlier version everything was working good.
So, Synology Team you must go to work and repair this problem.
