Described herein are methods and systems for selectively synchronizing locally stored data with data stored in a cloud storage repository. A client application can synchronize a portion of the locally or remotely stored content by choosing to synchronize data that is frequently used, data that is marked as priority data or data that was modified or otherwise accessed during a predetermined period of time. Other selective synchronization optimizations include predictively synchronizing data or content associated with frequently use or priority data and synchronizing data according to a priority score.
