Sorry to ask but I have been trying (and trying) to find out how to copy files, movies, YouTube file, etc onto my tablet from my PC and from the 'Net, but the techniques I cannot make work.
Do you (1)
already have the files on your PC, or (2) are you asking how to download them to there in the first place, or (3) moving them between PC and tablet?
In reverse order:
(3) There is a piece of PC Samsung software you can download and install which enables you to view files on your tablet after it's plugged-in via a USB port.
It'll show up as a new device on your PC (just like any other drive). Often, however, the device will be there but the files aren't visible.
I forget where the settings are on a Samsung tablet (probably "Settings"). Usually something like "Developer Options".
Then go to USB Connections and two main options appear.
"Charge device when USB connected" and "MTP". MTP needs to be enabled for the software to actually show all the files from the tablet on the PC. (Might have to reboot the tablet.)
Remember to set it back to charging on USB after you're finished.
(2) There are many ways to grab YouTube files (and many others).
One I use, (
not saying it's the best, but works well), is online from your web browser.
Free Online YouTube Downloader: Download YouTube Videos, Facebook and many others!
No need to install anything. Just copy and paste the URL of the video into SaveFromNet, pick a resolution (up to 720p max) and click go.
If you want to grab HD files from YouTube using this, you'll have to install the optional plugin.
Two main ways to download full-quality movies: from sites you pay to do so, or free ("illegally", unless they're in the public domain), from Torrent sites.
(1) See (3) above.
