Depending on the laptop you might find it has space for a second drive or an internal USB memory stick. The latter are available at 256G, which IIRC is plenty.

It's usually, though not always, also reasonably easy to replace a drive, so you could just fit a new larger drive. That would avoid having things dangling off or sticking out of the laptop, but you'd have to transfer Windows and what have you onto the new drive.

An internet search should show up a how-to on most laptops. The hard part is often learning how to get inside the case.
