alright thank you so much for all the info and help i will start compressing now, it will take a while so i will report back after its done

with 7z that is not working so i am using this instead
"a -t7z -r -mcrc=0 -m1=lzma2:d900m:fb=273:mf=bt4:mc=1000000:lc=4:lp=0 -mmt=4 -mx9"
is this good ?

Edit : nvm i just had to replace "txz" with "t7z"

TWOELV....Extract copy and replace in the folder "WPI_Inno 2.5", open ISS recompile and Test the installer.

wow it works but the thing is "pzlib+srep64+7z" is not giving me good compression i thought it was. So what tool can i use to properly compress using "pzlib+srep64+Lzma2"

Edit : seems like "pzlib+srep64+lzma" works with wpi and also cmd bench viper so i am compressing now hopefully i will get same ratio as lzma2

Edit 2 : "pzlib+srep64+lzma" didn't gave me good results :/ i need this method "pzlib+srep64+Lzma2" to support wpi

Lzma is used as an internal compressor in FA through fazip, Lzma2 you can even call it Pippo or Pluto, nothing changes, and it is controlled through the set of comp 7z, the only difference is you can obtained with LZ77 lzma16.04, where you can manually set the compression options in the arc.ini file.
if you want to push harder reducing few gigabytes with slower compression speed uses nanozip.

with pzlib+srep64+lzma2 i get 4gb
but with pzlib+srep64+lzma i get 9gb :/
same goes for pzlib+srep64+7z :/

so i will try nanozip and lZ77 and report back

Edit : tried LZ77 not good and Nanozip not good either and doesn't install with wpi :/

bueno no se ingles lo estoy traducciendo en google......
Mi consulta es que por ningun motivo este scrip funiona con mas de en un disco ya probe todo lo que dicen en los comentarios y respuestas pero nada sigue sin funcionar el detalle es que aparentemente si lo detecta pero no lo extrae, solo el archivo contenido en el primer disco ... solucion ???

Well I do not know English, I'm translating it on google ......
My query is that for no reason this scrip works with more than on a disk and probe everything they say in the comments and answers but nothing still does not work the detail is that apparently if it detects but does not extract it, only the file contained in The first disk ... solution ???

I change this WPI to support method pZLib+msc+srep64+lzma2
I tested on my own compression tool and working fine :D
