Abstract
A digital data processing system having an index file containing a plurality of file headers includes an arrangement having a file header processing portion for iteratively retrieving file headers from an index file and for establishing in response thereto a descriptor defining a directory in a directory tree, each descriptor defining the relationship of the corresponding directory to a parent directory in the directory tree, and a group vector processing portion, responsive to processing of a file header by the file header processing portion, for generating a group vector comprising a plurality of pointers to said descriptors, each pointer defining the relationship of a directory to one or more child directories in said directory tree.
