Found very old (13 years ago) LRZIP 32bit console compressors from net. Attached in below. Working from WinXP! Newest 32bit versions not available??

Description:

Long Range ZIP or Lzma RZIP

This is a compression program optimised for large files. The larger the file
and the more memory you have, the better the compression advantage this will
provide, especially once the files are larger than 100MB. The advantage can
be chosen to be either size (much smaller than bzip2) or speed (much faster
than bzip2). Decompression is always much faster than bzip2.

Lrzip uses an extended version of rzip which does a first pass long distance
redundancy reduction. The lrzip modifications make it scale according to
memory size.
The data is then either:
1. Compressed by lzma (default) which gives excellent compression
at approximately half the speed of bzip2 compression
2. Compressed by lzo which on most machines compresses faster than disk
writing making it as fast (or even faster) than simply copying a large file
3. Leaving it uncompressed and rzip prepared. This form improves substantially
any compression performed on the resulting file in both size and speed (due to
the nature of rzip preparation merging similar compressible blocks of data and
creating a smaller file).
4. Compressed by bzip2 as an rzip-like compression format.

The major disadvantages are:
1. It only works on single files. To get the best performance out of the
compression it is best to tarball all your files together.
2. It requires a lot of memory to get the best performance out of, and is not
really usable (for compression) with less than 256MB. Decompression requires
very little ram and works on small ram machines.
3. Does not work on stdin/stdout.
