System and method for identifying a segment of a file that includes target content

A computer system, comprising:

• one or more processors;
• memory;
• and
• one or more programs, wherein the one or more programs are stored in the memory and configured to be executed by the one or more processors, the one or more programs including instructions for:
• obtaining a file header for a file that corresponds to a plurality of separately indexed clusters, wherein:
• the file is divided into a plurality of segments;
• one or more of the plurality segments each include multiple sequential clusters from the plurality of clusters;
• and
• the file header includes a segment index that enables the device to identify a respective segment that includes requested content;
• receiving a request to seek to a respective position within the file;
• in response to receiving the request:
• identifying a first segment that includes content that corresponds to the respective position based on the segment index;
• obtaining the first segment;
• obtaining a content index that corresponds to a respective cluster within the first segment;
• and
• after obtaining the first segment and the content index, identifying respective content within the respective cluster that corresponds to the respective position based on a content index;
• after identifying the respective content, providing at least a portion of content corresponding to the file to a presentation device for presentation to a user, starting with the respective content.

A non-transitory computer readable storage medium storing one or more programs, the one or more programs comprising instructions, which, when executed by an electronic device with one or more processors, cause the device to:

• obtain a file header for a file that corresponds to a plurality of separately indexed clusters, wherein:
• the file is divided into a plurality of segments;
• one or more of the plurality segments each include multiple sequential clusters from the plurality of clusters;
• and
• the file header includes a segment index that enables the device to identify a respective segment that includes requested content;
• receive a request to seek to a respective position within the file;
• in response to receiving the request:
• identify a first segment that includes content that corresponds to the respective position based on the segment index;
• obtain the first segment;
• obtain a content index that corresponds to a respective cluster within the first segment;
• and
• after obtaining the first segment and the content index, identify respective content within the respective cluster that corresponds to the respective position based on a content index;
• after identifying the respective content, provide at least a portion of content corresponding to the file to a presentation device for presentation to a user, starting with the respective content.
