Here we discuss problems related to my utility, open a new thread, or better directly in the thread of Rinaldo, he's the expert of script with inno setup will give you valid information.;)

Zstd Compressor for windows & zstd v 4.4
 

i decided to give away my Zstd compression for windows
because i think it can go head to head with lzma :eek:
yes it can beat lzma normal and high modes but not ultra

special code it is pipelined through srep for maximum performance test the glory ;)


also i updated zstd to 4.4 the latest its getting better and better


Notes : zstd compressor for windows is only 64 bit, but i have posted 32 bit support on encode. ru forums i also gave away inno setup for it there too


Enjoy :)

packcmd = lz77 e -si -so <stdin> <stdout> -a1 -d30 -fb273 -mc10000 -lc8 -lp4 -mfbt4

this command is the top you can get that means lz77 aka(lzma renamed) will use best dictionary available


in short terms that means you must have at least 20 gigs of ram ..... yeah lzma can use bigger dictionary than 1024 mb ...
if i remember correct 1.5 gigs or now after the update around 4 which means 15 gigs and 40 gigs respectively .....


depending on your machine use -d15 instead of 30 or -d20 test a little

enjoy :)

EDIT1: well decided to give you many options since i am to the bone in lzma and lzma2
-mfbt4 command on lzma is power-very-hungry ram user and nasty one to use especially if your ram is limited
it will use 10 gigs of ram per 1gig of dictionary .... in short you can switch to -mfhc4 that uses 1.5 gigs ram per 1 gig dictionary
personally i havent used -mfhc4 at all so if you pull some tests please let me know

EDIT2: sorry forgot to tell above :P please dont yell for many edits i only have one mind
with this out of the way, lz77 replaces freearc-lzma in all aspects, this is why i posted it originally
freearc-lzma is outdated to the neck so why use it ?? arc.exe has lzma inside it already and you can just call it without having lzma in ini thi is why i renamed to lz77 to reverse conflict
the lzma inside arc.exe is also outdated to fazip.exe respectively :P

EDIT3: ok now because i want to make your live easy i will tell all my secrets like boss :P
fazip also hasnt been updated in while so its outdated to lz77
lz77 is the same code used in streams to produce lzma2 i use in xz command so all in all
if you wanna do it right delete lz77.exe and use

[External compressor:lz77]
header = 0
packcmd = xz a -txz -an -mcrc=0 -m1=lzma2:d1024m:fb=273:mf=bt4:mc=10000:lc=4:lp=0 -mmt=2 -mx9 -si -so <stdin> <stdout>
unpackcmd = dec x -txz -an -y -si -so <stdin> <stdout>

this line will produce a lzma variant exactly like lz77 and fazip and the lzma code inside arc.exe this is the most updated lzma code to this day
1gig dictionary usage 10 gigs ram is required

Final Edit :

Tests on your program and Corrections

Felice i had time today so i gave a go on your program which is very nice especially for new people in compression

i also give you my endorsement for considering advanced users in this section as well

i decided to make some corrections on this in order to help minimize its source

you dont need dll files as i injected them inside the applications exe now carry their dlls on their backs no need to have them in a file separetely

i removed some programs as well as they dont fit :P

i also updated srep 32 and 64 bit to the latest best version 3.93

Enjoy :)

@Panker the file "arc.ini" is updated when you start each application, so the changes that you made in the folder resource are lost and do not work at the next startup.
Moreover, with files that have modified in the folder 'resource' utility goes error with the methods that contain '+ lzma64', we must give the user the possibility of choosing any algorithm, and not the one that we like.:)
If you have any changes to the utility or any other updates, please send me the files, I will think about modify as best he can pleasure..;)

Felice i know what you mean .... let people have many choices is right i didnt remove the choices that you let people have but software updates fast even faster that we imagine

you can replace freearc-lzma with fazip

fazip excels in lzma coding by around 13% for 32bit and around 17% in 64 bit so :P

This is great, I understand, and other users will have understand, but if the utility has several choices let these operate without errors, and that the user can choose, on the contrary I would not have entered.;)
Moreover if there would be the possibility to enter the option lz77: "7z a -txz -an -mcrc=0 -m1=lzma2:d512m:fb=273:mf=bt4:mc=10000:lc=4:lp=0 -mmt=2 -mx9" OR xz: "7z a -txz -an -mcrc=0 -m1=lzma2:d27:fb=273:mf=bt4:mc=1000:lc=4:lp=0 -mmt=on -mx9"
Directly in the textbox of the utility would be a great thing, so that the user can modify the choice in the utility.

Felice i am uploading my masked compression project i am making my last adjustments


everything i am trying to tell you was for this moment you dont have to compress using one method when you can use everything all at once

did you know you can use reflate precomp lz77 zstd xz and deflating method all on 1 large bin file ???


sorry forgot to tell you :P

please let people modify the dictionary

because its ram dependant so people with less ram will never make it with lzma2 which can use 4 times the ram that lzma1 uses

Very nice update felice. This is a very powerfull tool.

I tried this program only SREP and was fine ..
it only works with SREP ... why?
when it crashes, always the same error .. and when I stop him from the button because it blocked ... from them is no longer moving.
Sin looked good your program :)

I really want to test, but i have an error "System.IO.FileNotFoundException
". the program crash quickly.
Win7x64

@rinaldo from what I see from the photo do not use it correctly, although I tested the utility in your way, it works equally..;)
Simply create a folder to save the compressed files, and not in a root directory of the system, where you have hundreds of other files, if you press' STOP 'while the program is running to read, for compressed files, risks of a crash' utility, seems obvious.:)
the utility is tested at 99% with the methods included in "Simple", attention that the algorithm contains "precomp" natively sometimes finds it difficult to compress some folders that contain files such as * .dll and others, it happened to me with a program called Picasa seems.

@ChronoCross checks that the root of the utility contains "MetroFramework.dll":)

only pre-stressed errors amazing .. use 043 only, otherwise they will always incompatible, because 043 is all in one and not the others, so the test will be more accurate with only a test exe .. regarding other methods, you should absolutely use the bat or programs in symbiosis.
