How do I check how much free space is on my usb? I don't see how I can do this, although I can access the usb stick's files when I insert it through Dolphin. Preferably a UI option, not command line.

You should look in the lower right corner of the Dolphin screen after you've inserted the USB stick. In the example, my USB stick has 3.7 GiB free.

free space on USB stick

If you don't see anything like that, open Dolphin, press Ctrl+Shift+, to bring up Dolphin Preferences. In there, click on General in the left pane and then on the Status Bar tab and ensure that Show Space Information is active.

Dolphin also allows you to examine the USB stick's properties. With the device inserted, move up to root and then to media. Open media. There you'll see, possibly among other folders, a folder with your username. Open that: you should see a folder bearing your USB stick's name (as seen by Dolphin). Right-click on that folder to get the window shown below. The General tab will show you what you want.


And, I know you asked for a route using the graphical interface but you can get the basic information, somewhat quicker, using the command line. See the last line in the output below on running df -h:
