In the laptop
In the file folder on the laptop.
In the explorer at windows
What is the question meant?
Plug in the USB stick, Explorer up, navigate to the USB stick and click on your "data".
At least under Windows…
Insert the stick into the USB socket and click with Explorer.
Very strange question…
The main thing is that you said something!
What do you think of if the stick doesn't appear right there?
Couldn't be inferred from the question. Does Windows make a splash when you plug it in? Do you see it in the device manager (press Win + Pause, then left device manager) under the category "drives"? Or in data management (press Win + R and start diskmgmt.msc)?
You should have said.
Then the stick is broken or the USB socket.
Did the stick work on another PC?
Do other USB devices work on this socket?
