  • System and method for file detection and usage during compaction
    Patent number: 10268400
    Abstract: A non-volatile memory system may include a controller configured for parsing a host file system, identifying a location of a host file system directory and tracking directory entries of files deleted from the host file system directory but having valid data mappings in the logical-to-physical mapping table. The controller may then store the location of the host file system directory, monitor activity in the host file system directory and track validity status information for use in optimizing a compaction process. The compaction process may include segregating into separate compaction destination blocks valid data based on the stored validity status such that data valid in both the host file system directory and the logical-to-physical mapping table is in compaction destination blocks separate from data having valid logical-to-physical mapping entries but associated with deleted host file system directory entries.
