I'm using Box API and it seems that, although all first-level folders and files (queried by https://api.box.com/2.0/folders/0/items) have correct sizes, the size of the root folder (queried by https://api.box.com/2.0/folders/0/) does not equal to the sum of the former, and is significantly smaller (~3-5 MB). On the other hand, I've noticed that the size of the root folder equals to the user's "space_used" figure (queried by https://api.box.com/2.0/users/me).
In other words, there are two strange phenomenons:
- The reported used space quota for the user is smaller than the sum of all files and folders
- The size of the root folder is also smaller than the sum of its direct child files and folders.
What could be the explanation of these facts? Is it a Box's bug, or am I missing something?
