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!!
