Compression ratio results are very dependent upon the data used for the tests. The program supports 7z, ZIP, RAR, CAB, ARJ, LZH, CHM, WIM, CPIO, RPM, DEB, GZIP, BZIP2, Z and TAR formats. In addition solid archives can be created. In Normal mode it compresses almost as original BZip2 compressor. ZLIB compression, which requires a COMPATIBLE setting of 11. - New -scrc switch to calculate total CRC-32 during extracting / testing. Tar download - 7-Zip 18. RLE is probably the easiest compression algorithm there is. An even smaller file of 40 bytes can be achieved by using an input containing entirely values of 251, an apparent compression ratio of 1147480.
