Important: removed xz lib 5.6.1 from all compressed files,
now we are using release 5.4.1 because it is stable
(CVE-2024-3094: liblzma backdoor)
Console application to compress and extract files in the .val format, when
functional it can be used to replace tar files, the advantage is that it
will handle any previous versions without problems, it is almost as fast as tar,
for the moment it can generate .val files in gzip, bzip2, bzip3, lz5,
brotli2, lzop2, Zstandard, xz and LZMA, but more compression methods will
be added like our DLL version of this console application, a lot need
to be done yet
Works on Windows 10 or above
////////////////////////////////////////////////////////////////////
Header information for Parolin:
These compressors are available in the now outdated DLL
Parolin, the console version don´t support yet all these
compressors but will do it soon
the following information can be used to detect a compressed file
Notice that some formats like bzip3 and gzip2 have more than one
header for it, and you need to handle it
{ compress, 2, "\037\235" },
{ gzip, 2, "\037\213" },
{ bzip2, 3, "BZh" },
{ lzip, 4, "LZIP" },
{ lzma, 6, "\xFFLZMA" }, (this is not correct, lzma don`t
have a pre-defined header that
can be used to detect it, brotli too)
{ lzop, 4, "\211LZO" },
{ xz, 6, "\xFD" "7zXZ" },
{ lz4, 4, "\x04\x22\x4d\x18" },
{ zstd, 4, "\x28\xB5\x2F\xFD" },
{ val, 4, "\x56\x41\x4c\x50" },
{ gzip2a, 4, "\x52\x53\x50\x47" }, (this moment this isnot
in use anymore)
{ gzip2c, 4, "\x41\x52\x5f\x5f" },
{ gzip2c, 4, "\x41\x52\x5f\x5E" },
{ bzip3, 4, "\x41\x52\x5f\x32" },
{ bzip3, 4, "\x41\x52\x5f\x5d" },
{ lzop2, 4, "\x41\x52\x5f\x53" },
{ lz5, 4, "\x41\x52\x5f\x56" },
{ brotli2, 4, "\x41\x52\x5f\x55" }, // brotli2 has a header
{ compress2, 4, "\x41\x52\x5f\x54" },

Added doxygen documentation to xz library, minor modifications.
What is new in version 0.8.4 build 6839 30/dec/2024 16:05 Codename Taylor
We detected a problem with the library xz 5.4.1 regarding multi-threads,
the sample project just slow down the compression process if
more threads than one is selected, and maybe we can help,
we will try to generate a variant of xz with up to three
threads running concurrently to speed up code execution,
the normal for a multi-thread software is to speed up
with more threads running, more about it soon, also, the
compression level in multi-thread mode is controled internally,
maybe this is the reason that it slows down the compression,
finished the docs for Zstandard.
What is new in version 0.8.3 build 6828 30/dec/2024 14:51 Codename Dunn
Fixed a bug in the Zstandard handling of the multi-thread,

important: Zstandard don't use multi-thread for decompression,
at least until we modify it to use.
