Hidden Image Explorer is the type of handy application that helps you clean your phone’s storage, and keeps you from getting the often untimely and inconvenient alert while you’re recording important memories through your camera — 

“Memory full!”

“Insufficient storage”

“Storage space running out”

You’ve already erased a number of videos and photos, and yet there still isn’t enough space. What gives?

This app will help you get to the bottom of this mystery. It scans the files in your phone and detects hidden images – photos in your phone that you never consciously saved – like cache files. 

Hidden Image Explorer lets you delete cache images – and other important hidden files that have been eating up your memory – from the platform itself; you don’t have to look for them by hand just so you could delete them.
