FILE MERGING File merging is a feature of LZX which enables compression to be increased, often very significantly, by allowing data from one file to be compressed using the knowledge of previous files in the archive. This feature, unique to LZX on the Amiga, often improves compression by 300% or more! Example This feature is very useful when compressing text files and source files, where there is often a large amount of text common to many files. Example There is also a significant advantage to this feature when compressing a large number of small files, since the data overhead of re-starting compression for each file is now removed. This is particularly true when compressing ".info" files. Example Even decompression time is improved, since there is now much less compressed data to procress. There are only minor disadvantages to file merging, which appear when deleting files from a merged group, or extracting only some (but not all) files from a merged group. To see the advantages of file merging first-hand, try recompressing the LZX distribution archive with LZX; LZX will compress the three executables (for the 68000/68010, 68020/68030, and 68040/68060) down to a tiny size because they are fairly similar.
