How can I transfer my laptop data to the USB stick?

Since my old laptop is no longer charging (see question 1 from me) I can now get a laptop from the production school where I also had the old laptop. But I have to transfer my data from the old laptop to a USB stick in order to then transfer the data from the stick to the new laptop. If you have a lot of questions, why don't I transfer the data from laptop to laptop? The answer is simple: I have to bring the laptop back first before I get the new one.

P.S.: There are data from many games upstairs where I'm already very far; Data from my YouTube videos and lots of private photos.

Can you help me?

That works, the stick just has to be big enough.

But how does it work?

I've never done anything like this before

You put the stick in the laptop, the stick will then be displayed as a drive in the file manager. Now all you have to do is copy the files from the laptop to the stick.

Thanks
