I meant the contrary it has worst ratio
I tried few times with mutliple games pzlib and ztool
pzlib gave better ratio , weird

Does pzlib is able to restore them back?

No, ZTool gave better ratio at every game file I have tested, that's why Razor12911 made it private.
Unlike pZLib the parameter "-x" is not for the ultimate settings in ZTool. To gain the best ratio from ZTool the parameter is different. And ZTool is also Faster & more stable than pZLib.

Ohh i didnt test it with ultimate settings parameter , i know it is really faster and stable.

Do ya know why ztool gives more ratio than pzlib?
Because ztool uses reflate libs even when detecting zlib streams(m1)

A week ago I tested with a 1GB file from jc2. pZlib 1350 gave 2.13GB and ztool gave 2.2GB.
Ofc pzlib 1350 was faster, while giving a smaller ratio.The 2.2GB file became 610mb after processing by srep, and 2.13GB by pzlib became 536mb. So it's proved that ztool uses reflate, which causes better ratio.

Did you update pzlib 1350 ?
I had decompression errors with 17 gb files

[78372]

Yep, but you have pzlib v3, use that
ztool is faster than pzlib 1350 in most cases. Very few games are processed faster(about 2x) by pzlib 1350

i get error crc when decompression..
How to solve?

Can anybody help me, how to solve decompression problem with pzlib compressed data. I have already compressed some files of max payne 3 with pzlib v3. Compressed ratio became 44.9% from 6.78 GB - 3.05 GB. But when i'm decompressing this compressed file with WPI by including pzlib, some files were not extracting. I don't know why? I using compression method as, pzlib3+srep+delta+exe2+lzma2:ultra:a1:mfbt4:d518m: fb273:mc10000:lc8.
Please help me......

Do not use stdio @compression !

hi guys. i am using razor12911's IC 3020 UA2008R2 modification, and i am having some problems with pzlib. the game i am trying to compress, syberia 1, has zlib streams inside the cmo folder in the root folder of the installed game, but when i try to install my repack after using pzlib on the folder with the zlib streams, the data/cmo folder, i keep getting a 'unarc returned an error error code -11 decompression fails - archive is corrupted' error and i know it has zlib streams because i scanned the folder with zlib checker. any ideas whats going on?

the cmo folder is only 95 mb but i want to get the hang of using pzlib.
please post back, i am frustrated and dont know why its not working.
ive tried using pzlib by itself which results in a larger file and pzlib with lzma both using UltraArc 2800 R2 and get the error code -11 with the second attempt.
any feedback will really help. thanks.

If you are using -f option remove it also try compressing from file to file instead of stdio.

hi guys, thanks for helping me with my pzlib question. i am still having issues so i thought i would post my arc.ini info here to further assist you all in helping me resolve my issue.

- arc.ini from F:\UA2800R2\Resources

My Method:
tor = srep+exe+exe2+delta+dict

Example (; = Disable)
;tor = /$File=srep+Lzma2/$Deflate=pzlib+srep+lzma:176mb:normal:bt4:273:mc10 00000000:lc8
;tor = precompmt+srep+lzma2
;tor = antiz+srep+nanozip

unpackcmd = 7z x -txz -an -y -si -so <stdin> <stdout>

[External compressor:zstd]

please take a look at my arc.ini files and tell me if i did anything wrong there. also i have raw2hif.dll hif2raw.dll pzlib.exe and cls-reflate.exe in my IC 3100 include folder. i know i could use CIU instead but i like the style of this app and its similar in design just a bit older. let me know if i need to change anything in either of the arc.ini files.. thanks!
