Collections enable you to organise your assets in a meaningful way, such as by subject. For example: if you had multiple assets relating to cars, you might want to group these assets together, by placing them into a collection called 'Cars'. That way, all the assets that are associated with cars will be in one place, thus making it easier to find them. You can also place one or more collections within another collection. A collection that is placed inside another collection is known as a sub-collection. You can have multiple sub-collections within a collection if you wish.
Below you can see an example of a collection which contains multiple assets. In the example below you can see that the collection is called Animation, and this contains assets associated with animated films.
You can see how many items are inside a collection by viewing the details at the bottom of each collection tile.
