Before items are deleted they might end up in a user’s trash. The trash can be
managed by a user through any of the Box apps, and by an application via the
API.
Box uses a two-stage process to remove or trashfiles, folders, and
web links before permanently deleting them.By default, items can be restored after they are trashed within a 30 day
time frame before they are purged. The purge window can be modified by
an enterprise administrator.More details can be found in the Box community article on Managing Trash
