Different sizes obtained with compression formats

    Hello,

    Which archive compression to use preferably and why so big size differences?
    As an example, a site has a total of 447MB uncompressed files in folder.
    With ZIP I get an archive of 257MB, while with Gzip I get 241MB and with TAR I get 465MB!

    – Isn’t TAR supposed to better compress files or am I wrong? Only Gzip gets better results than ZIP?

    Furthermore, TAR archives are not fully un-compressed in local Windows PCs and need to be extracted on server in order to obtain all files.

    – Is there a software that would allow to correctly un-compress TAR archives on Windows?

    I would much appreciate if someone can explain this further, thanks.

    HI @dsl225
    Tar is just bundled files together, so the file size is not small as zip, if you use Tar.Gzip, it will be just as good as Zip.

    Is there a software that would allow to correctly un-compress TAR archives on Windows?

    hmm I see on Windows, Winrar does this really well, or you can use the command line Tar by download Tar for Windows: https://gnuwin32.sourceforge.net/packages/gtar.htm

    Hope that could help ^^
