Quickly Find What Folder Holds an App in iOS
For those of us who have a bunch of apps contained within iOS folders, it’s fairly easy to misplace apps that aren’t used often. To quickly find out what folder contains an app, just swipe to the right of the iOS home screen to bring up Spotlight search, then type the name of the app into Spotlight. Alongside the app name you will conveniently find the name of the folder which holds the app.
While you’re in Spotlight search results, you’ll find that tapping on the app name launches it directly from Spotlight as well, just like in OS X. Chances are if you can’t find an app because it’s buried in a folder, this will be the quickest way to get to it.
You’ll need at least iOS 6 to be able to find the folders holding apps.
