Techniques for the aggregate and hierarchical display of grouped items spanning multiple storage locations are described. Some techniques may aggregate items in response to user input identifying a scope for item retrieval. The user input may identify a scope such as selection of a local storage location or a search query for retrieving items. The aggregated items may span multiple storage locations and include items within the identified scope and related items outside the identified scope. A group of aggregated items are presented in a hierarchical display within a user interface. The hierarchical display may visually differentiate items inside and outside of the identified scope, and may identify parent-child relationship between related items. An aggregate header for the group of aggregated items may be displayed indicating total items in the group and a status for items in the group within the identified scope. Other embodiments are described and claimed.
