Your folders become Chests
When you import bookmarks from Chrome, Caves of Wonders (CoW) places them in an Imported Cave. Your existing folders become Chests, which are the folders inside a Cave.
Continue organizing from there
You can create inner Chests, drag Chests to a new position, and move bookmarks into the Chest where they belong. This lets you keep your familiar organization while giving it room to grow.
Import Chrome bookmarks without losing folders or learn more about Chests.
