After months of beating my head against a wall with storage issues on my Samsung s6  I finally was able to solve them with this app within a few minutes. Android/Samsung take note. This is the kind of thing that should be built into the phone. When undeleted temp folders from downloads end up taking up 5g of your storage space... and you can't delete them  you need an app that lets you see them. This saved me the cost of a new phone. Thanks Ivan.
