### Remarks

Initially this is 0. As you download AssetBundles to the cache, this will increase. If insufficient space is available in the cache to store a requested AssetBundle, the least-recently-used cached AssetBundles in the cache will be iteratively removed until enough space is available for the new AssetBundle.
