In general, eBook files don't usuallytake up that much space unless there's a lot of images in them. Polish Books has an option to compress images, but only for ePub/AZW3.
You can run a Save to Disk > Save single format to disk and just stick them on an external drive.
Or just delete the formats you don't need anymore. You can re-convert later.
