摘要：
A method for compressing a set of file structures in a flash memory subsystem is disclosed. During a clean-up operation, a sibling chain of the file structures stored in a logical block of the flash memory subsystem is traversed. If a file structure is followed by deleted file structures in the sibling chain, then the file structure is transferred to a spare logical block and the sibling pointer of the file structure is programmed bypass the deleted file structures. If a deleted file structure in the sibling chain is referenced by a previous file structure in the sibling chain, then the deleted file structure is transferred to the logical block and recycled.
