Resynchronizing metadata in a content management system

Abstract:

A client can resynchronize tree data structures representing a server, local, and sync state of content items in an account. In some aspects, the client crawls a storage to identify content items at the client. Based on the crawling, the client identifies a local set of content items on the storage and metadata associated with the local set of content items identified on the storage. Based on the metadata, the client constructs a local tree data structure representing the local set of content items on the storage at the client, the local tree data structure including a respective local node representing each of the local set of content items. The client then stores the local tree data structure on the client.
