Manage Your iWork Documents on Your iPad
The data for your iWork documents is stored in files on your iPad, possibly on your Mac or PC, and also sometimes on shared WebDAV (Web-based Distributed Authoring and Versioning, used for collaboration and managing of files on the web) servers and, as you will see, on iCloud, if you choose.
You can also take advantage of the new iWork for iCloud feature that allows you to use online versions of the iWork apps and have your documents automatically accessible on all your iOS devices and on iCloud.
You can use a Windows-compatible browser to access your iWork for iCloud documents, and then work with iWork in iCloud by using that same browser.
One feature that makes iWork for iOS successful is that the iWork team has made it easy for you to move documents around and work on them in whatever environment you want, from your desktop to a mobile device such as your iPad.
What matters is that you can get to your documents, read and write them, and share them with people. It’s also critical that you can get to documents that other people share with you without either one of you having to jump through hoops.
Deep down inside the iPad operating system (iOS) are files and folders, but most of the time you manipulate them indirectly through apps. When it comes to apps, the files and folders are in a special area reserved only for that app (it’s called a sandbox).
Some apps such as the iWork apps can read files from servers such as WebDAV; if you select one of those files, it’s copied into the appropriate place on your iPad for you to work on it.
The storage areas for files on your iPad are kept separate for each app. If you install Pages and then remove it from your iPad, your Pages documents disappear along with the Pages app. Before uninstalling any app from your iPad, make certain that you have backed up any files you’ve created.
