ABSTRACT:
A method of identifying file format, converting file from assumed format and bit ordering to user-definable format, dividing file into blocks, determining frequencies of occurrence in blocks, creating first set of frequencies of occurrence less than and equal to most frequently occurring integer, creating second set of frequencies of occurrence greater than the most frequently occurring integer, creating third set of differences in first sets, creating fourth set of differences in second sets, replacing third and fourth sets with polarity indicators, summing polarity indicators, determining sum percentages, pairing percentages, determining pairing maximum number, determining statistics, determining maximum of statistics, assigning result to converted file, selecting another format and bit ordering and returning to third step, identifying converted file with maximum statistic, and determining format and bit ordering of file to be that of assumed format associated with converted file identified in last step.
