A system and method for a block based differencing algorithm which includes the ability to limit memory requirements regardless of source file sizes by splitting the source file into optimally sized blocks. The invention allows the blocks to be processed in any order allowing in-place operation. Further, the present invention allows a second stage compressor to match the compressor blocks to those used by the differencing algorithm to optimize compressor and decompressor performance.

A method to efficiently detect, store, modify, and recreate fully or partially duplicate file forks is described. During archive creation or modification, sets of fully or partially duplicate forks are detected and a reduced number of transformed forks or fork segments are stored. During archive expansion, one or more forks are recreated from each full or partial copy.

A method for effective color modeling for predictive image encoding. Colors are processed on a binary basis, when each color index is treated as a binary value. Binary digits are processed sequentially with the use of context-based approach. The context is calculated as a unique combination of binary values of already processed digits, the position of the digit currently being processed and an additional identifier from a limited set of identifiers that describe differences between the predicted color index and the averaged color index being reconstructed during bitwise processing. Color mapping, table operations and a special rules for efficient difference identification are proposed as major enhancements of the method.

A method to efficiently detect, and thus store, approximately duplicate or most likely duplicate files or data sets that will benefit from differencing technology rather than standard compression technology. During archive creation or modification, sets of most likely files are detected and a reduced number of transformed file segments are stored in whole. During archive expansion, one or more files are recreated from each full or partial copy.

A method of dynamically creating a two-stage self-extracting archives. During the archive creation process the executable code segments for inverse algorithms are selectively added to the self-extracting archive, but only for those algorithms applied during archive creation. This results in a considerably smaller size of the self-extracting archive. Additional space savings can be achieved by reprocessing the original data to eliminate the use of any algorithm applied in the archive creation which resulted in less savings than the additional size of the corresponding inverse algorithm. The selected inverse algorithms are themselves compressed. A compact inverse algorithm is provided as ready-to-execute code, which restores the selected inverse algorithms to an executable state, and then causes them to be executed on the compressed file data.
