Abstract: Embodiments of the present invention relate to systems, methods and computer storage media for facilitating the structured storage of binary large objects (Blobs) to be accessed by an application program being executed by a computing device. Generally, the manipulation of Blobs in a structured storage system includes receiving a request for a Blob, which may be located by way of a Blob pointer. The Blob pointer allows for the data, such as properties, of the Blob to be identified and located. Expired properties are garbage collected as a manipulation of the Blob data within a structured storage system. In an embodiment, the Blob is identified by a key that is utilized within a primary structured index to located the requested Blob. In another embodiment, the requested Blob is located utilizing a secondary hash index. In an additional embodiment, the Blob is locate utilizing a file table.
