Methods for packing and unpacking files in a multi-level hierarchy in single actions. The methods operate in memory through using one file pointer for the archive file in recursive calls to the packing and unpacking methods, for accessing files in multiple nested levels. The packing and unpacking are performed in memory, and no temporary files are written to a storage device, thus saving on storage and processing time. A user can also store or retrieve files selectively from an archive file.
