That’s too much work. How very sad of OS X to not have the same flexibility as Windows.
LOL - you'd really write anything they told you to, wouldn't you?
"Sad"? LOL!
Tell your masters it won't work - Jobs can't be stopped.
LOL!
There are also things that are easy to do in a Mac but harder in Windows. Both have their pros and cons, but I can't honestly say that I've ever had to do what you are asking to do. Do you actually keep stuff in the Trash that you don't want to delete? Isn't that sort of like storing food that you might want to eat in your kitchen garbage can? Do you normally throw things that you want to keep into garbage cans?
And for the record, if there are specific files I want to delete without touching the Trash, I'll open up a Terminal window and delete them from the command line. Once they are in the Trash, the Mac assumes that it's garbage that you actually want to throw away.
