You don't have to convince me of anything. You're arguing both sides of the coin. I'm done; I'll figure it out myself.
On one hand, you have VLC saying in the image that it'll be dumping media if it fills up without notice, and on the other hand, you're showing a second app screenshot that appears to actually have storage instead of caching.
So basically, I'm not hard to convince. I just require a coherent answer. I'm at this point assuming that you're trying to state that the second app does in fact do media storage, and not caching. Good enough. Just understand that when you run off on the word cache (not cash, btw), you have to understand that in computer terminology, cache is subject to replacement. Just like geocaching, someone finds it, they empty and replace their army man and candy with a quarter and some sweettarts. So when VLC states it is caching, that's not a convincing storage argument. Storage isn't caching; only a user can change storage content. Very different concepts, and while I really don't want to be pedantic, the "some time" you're complaining about is based on your confusion in how you argued the concepts visually.
I'm done. I have my info. Have a nice day.
