"This paper provides a theoretical understanding of algorithms and data compression archivers created on their basis. Details the calculation of redundancy information, the compression ratio, the amount of information entropy of the text in the selected user's file. Based on Huffman and calculation formulas developed a program in the development environment Delphi «Analysis of the effectiveness of data compression and archiving,"" which allows you to compress the files selected by the user selected output tables archiver with the original and compressed file sizes, as well as to analyze the effectiveness of compression without making itself file compression that allows you to save you time. A randomly selected files are analyzed compression efficiency, the results of the analysis are presented in the form of screenshots from the program. The diagram compression ratio for one of the files."
