Why is my tablet not detected by my PC?
Your tablet works like a computer, hence the fact that it is not recognized by your computer.
Indeed, it is not detected and will not be connected as an external device.
To transfer files from your computer to the tablet or vice versa, use the micro-SD slot to insert a memory card or share the files in a network.
For more information on file sharing, please consult Windows® Support
So, it is saying to either use a micro-SD memory card, or network the tablet to share files.
