• providing to a first client, having first file format processing capabilities, first information that enables the first client to access respective content in a first file format;
• providing to a second client, having second file format processing capabilities different from the first file format processing capabilities, second information that enables the second client to access respective content in a second file format different from the first file format, wherein:
• the first information identifies a first set of file portions that can be combined to generate the respective content in the first file format;
• the second information identifies a second set of file portions that can be combined to generate the respective content in the second file format;
• and
• the second set of file portions includes one or more shared file portions that are included in the first set of file portions.

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

• obtain information that enables distribution of content to a plurality of clients having different file format processing capabilities;
• provide to a first client, having first file format processing capabilities, first information that enables the first client to access respective content in a first file format;
• provide to a second client, having second file format processing capabilities different from the first file format processing capabilities, second information that enables the second client to access respective content in a second file format different from the first file format, wherein:
• the first information identifies a first set of file portions that can be combined to generate the respective content in the first file format;
• the second information identifies a second set of file portions that can be combined to generate the respective content in the second file format;
• and
• the second set of file portions includes one or more shared file portions that are included in the first set of file portions.
