I have a 7-inch Kocaso Android tablet with System 4.4.4 - (Is that KitKat?). I am very new to this device although I am familiar with computers and laptops. Is Kocaso a "good" device maker? I have installed an SD Card with 16GB. I want to be able to manage this card: Create folders, Move files, such as pictures from the "Gallery" to the card, set up directory structure, such as "Sally's Wedding", "Disney World 2016", etc. I have a device that takes the card and attaches it to a USB stick. I'd like to be able to move files to my computer. Can someone please recommend a Card Manager, plus documentation which helps me use it? Thanks.
