Local Storage uses the new Storage Access Framework to allow other applications to read or write any file in your primary storage and read from secondary external storage devices (such as SD cards). On Android 5.0+ devices, you can also select entire directories and rename files.

Note that this app is not meant to be used by itself (although we do provide some sample queries), but to be used to enable other applications access to files they would normally not be able to see - you shouldn't ever need to actually open this app!
