Moving ebooks to and from your iPad and your computer
Because iPad apps do not allow any outside access to data stored by apps, we need the COW app itself to move copies of its own data into and out of the iPad.
But the COW app doesn’t have access to your computer. There has to be a place to pass the files to your computer. That’s where Dropbox comes in.
The Forget button is for removing the connection between the app and your Dropbox account. Use this if you change Dropbox accounts for some reason.
The Disconnect button is for breaking the connection with Dropbox. This can be handy if for some reason the list of files in Dropbox is not updating. You can disconnect and then connect to start fresh.
