Question: Reduce the image and then expand the entire storage.

[Namexx]

Hello,

 

I would like to know how they reduce the size of the images and then, when the microSD cards are inserted into a card, they expand to fill the entire space. In other words, the same thing that Armbian images do when we use them for the first time: they are small, and then they occupy all the storage space.

I learned about this when I was using odroids... maybe armbian and raspberrys works in the same way:
