Here’s a question I get a lot: “Can you use USB flash drives on tablets, the same way as a desktop computer or laptop?”
The answer is “It depends.” If you’re using a Windows tablet with a USB port, you certainly can.
Some Windows tablets have a microUSB port. You’ll need to use either a flash drive with a microUSB end or a memory card for storage on these devices.

Android devices have a microUSB port. You can use a flash drive with a microUSB end on some Android tablets and phones. But not all. The devices have to support transfer to external storage.
For devices that don’t support a USB flash drive, you can transfer to another device via a sync cable or consider getting a wireless external drive that you control with an app.
