Great app with great support. Emailed dev Ivan  """"""""""""""""What exactly does 'System Data' refer to? Files your app can't read? Files on the same partition  but not located in '/data'? I need help understanding how this part of your app works."""""""""""""""" Got a same day response  """"""""""""""""'System Data' is the difference between all files DiskUsage found on a partition versus occupied space (total - free) reported by the partition."""""""""""""""" This app was a great help!""
