because some file can have virus or troyan and can be directly executed by error
I prefer this possibility, this is an option that administrator can activate or not
It is to me more logic that and account can see what is in an archive tar as a folder and not that a file can be expanded on my computer with how many sub folders wich can saturate a hard drive
if you want I can create an exe autoextract with full surprises and send you it
(no virus ,no troyan, just full off icon on your desktop..) It is very funny to have to eliminate 500 or 1000 icons on your desktop
