The native browser does not permit file copying. ES File Explorer does and is among the best to do so.
Follow instructions given here to put a shortcut icon for ES File Explorer on the home screen.
Pictures and movies (the media files) are either (a) still on the camera card, or (b) in the computer.
If the media files have been sorted on the camera, then they can be transferred back to an empty camera card (SD) or put on a USB memory stick.
Insert card and/or USB stick into the Minix. (Note that the card could be an adapter to carry a microSD (TS) card, and is inserted contact-side up. The image below shows the TS card part-inserted and the SD adapter also part-inserted).
When the instruction below says "click" it can also be "touch" for tablet or other touch-screen-based devices.
With the storage media inserted the power is switched on. The ES File Explorer icon is clicked.
The files and filing system is on display. The left column lists important storage and other major items that ESFE can help with.
We pay attention to (A) 0 = the storage on the Minix, (B) sda1 =
Folders are prepared on the Minix. We need to store our media files in some orderly manner.
Click on "0" and then click New (at the bottom). You will be given a window to choose File or Folder.
As I have done this several times (for illustration), my folders begin with the top one named "MyPics".
Under this one I made 3 folders and am about to create a 4th.
When you choose Folder, you are given a screen-keyboard and a window to enter a folder name. Click OK when done.
In this second example I am creating a folder inside the "EmmaDavid" folder - which can be seen in the top location bar (blue).
I have already created a folder called Oct2015 inthe EmmaDavid folder.
Having prepared Destination folders, I now go back to the Sources.
Click on the sdcard1 item at left and files on this card are displayed on the right.
A long click on any media file on the right brings up a new bottom menu and the ability to choose files to transfer.
Click in the boxes to choose files to Copy. (Do not check boxes for "Android" or "System Volume Information").
You can select everything by clicking the tick at top right.
Now click Copy (bottom line), and then click "0" in the left area.
Navigate to the destination folder (in my case ... MyPics > EmmaDavid > Xmas2014.
Then click Paste. Progress of the multiple file copy is shown (as below).
When done the media files can be viewed.
The files ending in .MTS are movie files. Click on a movie file for the first time and this menu appears.
You can click on the wee tick to "Set as the default app". I chose the 4K Movie Player - which works fine with those MTS files.
To start with there are player controls at screen bottom. These go after a second or two but can be obtained with a click.
All movies will play in sequence or can be repeated using the controls.
If a picture is clicked, for the first time, instead, then you get this menu ...
I chose the ES Image Browser instead of Gallery. This app gives thumbnails along the bottom of the screen.
The thumbnails disappear but a click will restore them and a menu option with which you can set a slideshow running in this folder.
It is a 3-vertical-dot icon in the top corner. Click to get options including SlideShow. You set slide intervals and let it run.
