It is easy especially if you are an old iPad user that you have a good handful of applications in your iTunes account. Sometimes it is easy to reach hundreds. We download them, we fiddle with them for a while and we delete them from our iPad and we forget. Sometimes we would like to retrieve them to reinstall or see if they have been updated, but they may have been removed from the App Store. Well we teach you how to manage your iPad apps so you don't lose any and so you have a cleaner account.

You can see how many apps you have by going to the applications section Bought from your iPad library in iTunes. You can see them in chronological or alphabetical order and also see which ones you have now on your device or all the ones you bought. If you want to reinstall some but the list is very long and you don't remember in which folder you put it, you can hide the applications by sliding your finger on them from right to left until the button appears Hide. This way you will have things clearer.

You can use various criteria to organize it such as developer, date, name, etc. Once you are there you can decide to clean up by sending them to the Trash or reinstalling them.

You can go to the bottom of the iTunes screen and you will see a message that indicates the number of updates that are available. If you click on that message, you will get a list of all the applications that have a update availableeven if they're not on your iPad. You can update everything at once or be selective and go one by one.

The problem would come when you want recover an application that is no longer in the App Store. This can also be fixed. The only condition is that you have made a backup copy of your Apps list on your personal computer. It is important to do this from time to time for this reason.
If your computer is a Mac, go to the Macintosh HD folder and open another folder called Users and find the folder with your name on it. Go to Music / Itunes / Applications. If you are a PC user, go to hard drive C: and Users / Your username / My Music / iTunes / iTunes Media / Applications.
Then you will find a list of all the applications you have had and it will be enough to drag the file to your iTunes so that it returns to your library and thus be able to reinstall it on your iPad.
