To the developer  thanks for making this. My folks are late smartphone adopters and constantly have their primary memory full of stuff. Maybe videos from countless WhatsApp group or some or other malware eating up space. You have saved me every time their phone runs out of memory. The Open in explorer feature and delete features along with the visualization make the app perfect. It looks like the WinDirStat of android. Thanks a ton again!
