Abstract
Methods, program products, and systems implementing random access data compression are disclosed. Data can be stored in a data structure in compressed or non-compressed form. The data structure can include a header block, one or more data blocks, and one or more index blocks. Each data block can include data compressed using different compression technology. The header block can include searchable references to the data blocks, which can be located in the data structure after the header block. The searchable references permit non-sequential access to the data blocks. The data blocks can be organized independent of a file system structure. The header block can additionally include references to the one or more index blocks, which can expand the references in the header block.
