It's overall structure is similar to the well known MS-DOS FAT file system. It uses a file allocation table (FAT) to keep track of allocated space and a hierarchical directory system where all of a file's metadata is stored in it's directory entry. Like the FAT file system, which groups disk sectors into clusters, the PS2 memory card file system groups flash memory pages in to clusters. On standard PS2 memory cards, the cluster size 1024 bytes, or 2 pages long. | ||
