Abstract
Storage optimizations by directory compaction in a file allocation table (FAT) file system. The method comprises determining if a cluster comprises a deleted content, indicating that the deleted content is deleted, and updating an entry of a FAT associated with the cluster to indicate that the cluster is free. The method may also comprise indicating that the deleted content is deleted and modifying a metadata of at least one of a file of the cluster and a directory of the cluster according to a specified protocol.
