2.6 Compound File Directory Sectors

The directory entry array is a structure that is used to contain information about the stream and storage objects in a compound file, and to maintain a tree-style containment structure. The directory entry array is allocated as a standard chain of directory sectors within the FAT. Each directory entry is identified by a nonnegative number that is called the stream ID. The first sector of the directory sector chain MUST contain the root storage directory entry as the first directory entry at stream ID 0.
