So I've downloaded a number of mp3 files for my classes through the Downloader and Private Browser app and the files are .zip files that are being extracted into some "default folder" in "archives" but 1) the mp3 files aren't playing when I click on them and 2) I can't find them through my file manager apps! I know they were saved to internal memory because I'm now getting warnings that my internal storage is low but I cannot find them by any other method and it's getting frustrating! I need to clear my memory and move these files to my SD card (I thought the default download location was SD but apparently not). Would there be any reason my file manager apps (ES Task Manager and Android File Manager) cannot find these mp3s?? Even when I go into the app folder itself, the data is not there. Any ideas for how to search files within internal memory of the S4? And I may not understand rooting, but would rooting give me better visibility into what's on my phone?
