Easiest troubleshooter I found Rather than trying to have pie charts breaking down storage by type and having a useless huge """"""""other"""""""" category  this app breaks storage down by directory and is thus far more useful IMO. In a handful of minutes I pinpointed and solved my storage problems. It isn't beautiful material design  but it is highly functional for the few minutes you need it for. Note that you can zoom in and out if the want to look at smaller files.""
