Hello, First, sorry for my bad english. I don`t know nothing about script and programming, but I have solved a problem that I had. I need a folder in a external hdd, this folder is part of my dropbox account. My problem is that when the drive is disconnected, dropbox think I deleted the folder and delete it from the cloud and other users of my company. I made a Script (with google help of course): Code: [COLOR="RoyalBlue"]on idle set a to "/Volumes/my folder" set b to POSIX file a tell application "Finder" if not (exists b) then tell application "Dropbox" quit end tell end if end tell return 3 end idle[/COLOR] And work perfect for me. Here the question: - Can I run this script but in background? (It's a bit annoying to have the application open all the time). - Any better way to do this ? THANKS A LOT to all !
