xtool:mzlib+srep+LZMA-MT

Output should be around 9.5 GB

Example for DiskSpan: xtool:mzlib+srep_new:1+LOLZ_NORMAL or xtool:mzlib+srep_new:1+lzma2

Thanks, gonna try tomorrow. So if I understand using only xtool:zlib only decompressed files for me but not compressed it again and hence I got that size
By the way, what does NORMAL mean after LOLZ? It means compression level or thread priotity?

Thanks
Also, what "MT" means?
LZMA2 and LZMA-MT, what is the difference between it? Is there any thread out there where I can read more info about compression methods and these special settings for them?

Lolz: From the bottom up, from the weakest compression to the strongest, but the stronger the compression, the more time will be spent on it. Normal, High, ... its just presets.
You can read all info about lolz here [But in Russian] [You can use the translator] https://krinkels.org/resources/lolz.264/

[KaktoR]

LZMA2 is used by 7-zip (multithread option is used by default).
LZMA-MT is used by FreeArc (FreeArc LZMA with 4x4 option, literally multithreaded. It will utilize max 16 CPU threads).

As for LZMA2 (it is basically just a predefined config name), you can read possible options somewhere on the 7-zip page I guess.

For the LOLZ_* names: These are just predefined configurations. FreeArc will read LOLZ as follows:

lolz{:options}

Where {:options} includes all valid options for this compressor.

So the preset "LOLZ_NORMAL" is just this:

lolz:d<expr:((0.45*freememory/11)-(32*1048576*2))/min(thread,16)/1048576>:mtt1:mt<expr:min(thread,16)>:mc1023

DSG reads your aviable free RAM and replace the :d option in lolz, same for the :mt option, just with your max CPU threads.

However you can write your own options if you want. lolz options can be read in english in the following folder "Resources\FINAL\LOLZ\Options.txt"

Pure uses LZSS like compression.

You may try to make a plugin for it.

Will it benefit in terms of compression ratio? I don't quite understand what is the reason of it and moreover how to make a plugin, I'm beginner, using methods present in DiskSpanGUI
