    The second stage uses a standard compression algorithm to compress the output of the first stage. It is quite common these days to need to compress files that contain long distance redundancies. For example, when compressing a set of home directories several users might have copies of the same file, or of quite similar files.

  3. ALZip - Wikipedia

    en.wikipedia.org/wiki/ALZip

    ALZip is an archive and compression utility software application from ESTsoft for Microsoft Windows that can unzip 40 different zip file archives. ALZip can zip files into eight different archive formats such as ZIP, EGG, TAR, and others.

    The file manager has a toolbar with options to create an archive, extract an archive, test an archive to detect errors, copy, move, and delete files, and open a file properties menu exclusive to 7-Zip. The file manager, by default, displays hidden files because it does not follow Windows Explorer's policies.

    This means that compressed archives with the UC2 file extension can hold almost 1 million files. .uca PerfectCompress [17] Windows: Windows: No Based on PAQ, RZM, CSC, CCM, and 7zip.

    Large file support (up to approximately 16 exbibytes, or 2 64 bytes). Unicode file names. Support for solid compression, where multiple files of similar type are compressed within a single stream, in order to exploit the combined redundancy inherent in similar files. Compression and encryption of archive headers.

    A match length code will always be followed by a distance code. Based on the distance code read, further "extra" bits may be read in order to produce the final distance. The distance tree contains space for 32 symbols: 0–3: distances 1–4; 4–5: distances 5–8, 1 extra bit; 6–7: distances 9–16, 2 extra bits; 8–9: distances 17–32, 3 ...

    en.wikipedia.org/wiki/Lempel–Ziv–Markov_chain...

    Decompression-only code for LZMA generally compiles to around 5 KB, and the amount of RAM required during decompression is principally determined by the size of the sliding window used during compression. Small code size and relatively low memory overhead, particularly with smaller dictionary lengths, and free source code make the LZMA ...

  9. Executable compression - Wikipedia

    en.wikipedia.org/wiki/Executable_compression

    Executable compression can be used to prevent direct disassembly, mask string literals and modify signatures. Although this does not eliminate the chance of reverse engineering, it can make the process more costly. A compressed executable requires less storage space in the file system, thus less time to transfer data from the file system into ...
