I know PreComp 0.43 and its positive and negative side in the compression and decompression.:D
But shit i have had an oversight, i had not inserted the "n" in the line of the *arc.ini files.:o

In fact so
Code:

"packcmd = PreComp -intense0 -c- {options} -o arcpackedfile $$ $$. tmp $$ arcdatafile $$. tmp"
NOT working...

So
Code:

"packcmd = PreComp -intense0 -cn- {options} -o arcpackedfile $$ $$. tmp $$ arcdatafile $$. tmp"
works perfect.:)

Soon i upgrade my program with your method, thank you for your work.;)

I will be glad to see your work with xz :D
hope you like! it it took almost forever to complete :P

Panker1992 if you like lzham you need to test lzmh.

panker1992 24-11-2015 05:16

Mr gozarck there are several reasons why i like lzham
~first: its compression is close to lzma
~second: it can decompress x2 ~ up until x8 faster than lzma
~third: has andler32 inside
~fourth: the lzmh i have seen is from 2007 and its state is very beta at the moment

PS: can you show me how to inject dll inside exe files ??? i need to inject lzham.dll inside lzham.exe

PS2: do you have a recent lzmh ?? or and updated version of it ?? if i find a working copy i may as well put it in good use

PS3: i really like your work :) thanks for reflating bat files

Panker1992 yes lzmh its old and beta and i have the same version like you. Dont worry about beta versions, remember we are using compressors in alpha version. freearc precomp nz lzham fazip.
and lzham is a very nice project and i give +1 because the project is It is in continuous development.
i use "enigma vitrual box" to inject dll to exe and other things too.
i like your work too, so go on my friend.

alright, you gave me enough reason to support many tools right now.
tho I find lzham and zstd very complete set of tools .
will test lzmh and update this set of tools as well.
i am currently working on a project called "Masked Injection" you dont know what i am talking about now .... but once its ready you will be amazed, the same feeling i get as i am coming to its beta phase.

Sharing is Caring after all :)

EDIT: Uploaded a Bink - Bk2 converter i injected it myself and also i wrote that cmd file as well ..hope you like it !!
EDIT 2 : Thanks for lzmh will test it :D if its promising i will also update my tools here :)
EDIT 3 : it seems i cant make lzmh work right now (windows 10 machine) but trying the new injected lzham on 7z :P thanks again gozarck

hello panker 1992. I allowed myself to change the compression order in: precomp+msc+srep64+zstd+xz
on 1 file 150mo result is: 60mo
with your method: precomp+msc+srep64+xz result is 44mo
do you know why with xz and zstd together compression is less good?
I was thinking the 2 associate give best results.
Thank you

panker1992 19-12-2015 08:03

the reason is simple ..... different algorithms give different results
for example srep, lzham, lzma and xz(lzma2) all use the same variant of lz77 original algorithm on the other hand zstd has lzo variant algorith with fixed dictionary and entropy encoder all on it ... so it trades its ratio for a maximum of 500 mb per thread per sec


now to get to the point srep + xz = lz77 + lz77 so it gives its best ratio on the file
srep + zstd + xz = lz77 + lzo + lz77 so the xz cant perform its best on top of an lzo algorithm

i hope i got clear on this, please ask any questions that you like
if i can answer it will do for sure :)

kenzo34 19-12-2015 08:40

thank you Panker1992 for your reactivity
I understand now the difference of ratio.

panker1992 19-12-2015 09:01

Ratio-mania and compression-mania started because i wasnt able to fit many many data on dvds

Now after several years i have tried to learn everything i can on how compression algorithms work

Your welcome kenzo hope you reach your goal on compression :)
