The archiver works under following scheme:

  1. Set of filters.
  2. Burrows-Wheeler Transform (BWT).
  3. Advanced "Move To Front" (MTF) or "Sorted Inversion Frequencies" (SIF).
  4. 1-2 encoding.
  5. Arithmetic coding with use of Peter Fenwick's structural model.

The archiver has some methods of data preprocessing for improvement of compression:

The compressor is featured in the BWT comparison.
