You are correct oh Texas gal. It shows up automagically on all drop box computers/devices.

I don't know if the other services offer the same but it also has a restore function should you want to go back in time to a different version of the file or to recover a file accidentally deleted within the last 30 days.

With the Pack Rat add on for Pro users it will never delete the changed/deleted files, and they don't count against your quota.
