I use Dropbox for work, and for my own writing/work I do on my own. I have dropbox everywhere (I love it) on my imac at work, my laptop, imac, ipad, iphone at home and everywhere I go. My iMac at work is not really secure (though i do have a password for the imac) and I worry that folders could wind up getting deleted etc. Not on purpose, but during some maintenance etc? All my writing is in dropbox and that's the folder I worry most about losing. So I've been choosing not to keep that folder, through dropbox preferences, on the work imac. It is inconvenient at times though, and I'd like to be able to keep that folder available there. Is there some way I can protect that folder, or perhaps the whole dropbox folder, from being interfered with by anyone but me. Some way to do that that wouldn't interfere with any Dropbox functionality? thanks!
