Your tablet should have "otg" capabilities which means you can plug in a usb drive. Best option is buy an otg usb drive with micro usb on one end and regular usb on the other. Then you can transfer files using a file manager app.
Some file manager apps have a wifi transfer feature that, while on your home wifi, provided you with an ip address which you enter in your pc browser bringing up a file transfer tool. This would eliminate need to use usb to transfer. Of course you can use a microUSB cable to connect you tablet directly to your PC and transfer files that way.
You can find OTG usb cables that will allow you to connect a regular USB drive (format FAT32) to the microSD as well.
Also, if you have Netflix, you can download movies/shows for offline viewing.
Fyi I like VLC apo for watching my movie files on tablet.
