Under the graph of your iPad's storage space, you'll see a list of every app on the device, listed in order from largest â taking up the most space â to smallest.
The numbers displayed for each app include both the app itself and any data files the app is using. For example, the Music app might be near the top of the list, because while the app itself is lightweight, the music files it stores tend to take up a relatively large amount of space. You might also see your video apps near the top, because videos are large.
For details on any app, tap it. On the app's details page, you can see how much space it's taking up and have the option to delete the app and all of its data, or just delete the app and leave the data behind.
Tap "Delete App" to remove everything â app and data. This recovers the most space possible, and is good if you need to reclaim a lot of space in a hurry. Unfortunately, you will lose your data in the process, though. Tap "Offload App" to delete the app from the iPad, but leave the data behind. If you later reinstall the app, the data will still be on the iPad and you can carry on as if nothing happened. This is a good option to choose if you only need to reclaim some space temporarily and plan to reinstall the app later â and the app is large but the data doesn't take up a lot of room. You won't see much benefit from offloading a music or video app and leaving the files on the iPad.Original author: Dave Johnson
