Warning! - You should double-check the:
Dropbox Preferences | Import | Camera Upload | Change AutoPlay Settings
because Dropbox will automatically change all your computer's Control Panel AutoPlay settings:
Control Panel\All Control Panel Items\AutoPlay
Warning! - Keep your Dropbox folder on your boot drive (probably C:).
When Dropbox does not detect your Dropbox folder, it will attempt to recreate it in it's default location (C:\Users\YourUserName\Dropbox).
Dropbox won't work correctly should the Dropbox folder ever become inaccessible.
Support - No telephone support. You must use email, Web form, or Twitter for help. Lots of complaints about slow poor tech support.
