why can you trash, rename or move an open file in mac os?

[dgg32]

Hello everybody. I am new from the win site and just wonder that in mac, you can rename, move or even trash a file when you still have it opened in preview or textedit.

In win, such action will be stopped by the message "can't do that, the file is open somewhere". Would that data going to be kind of homeless or become a "ghost"?

Just curious and want to learn something from you guys. Thanks for all sort of answers.

Greeting!!

because the file isn't deleted from it's place until you empty the trash

i think the term ghost would be best, you can move anything while open, not sure how to explain it further lol

Even after you move it or change its name, mac os is still able to find it?

Every file in Mac OS X has two "files", the resource and the data fork.
