How to Split BIN file compressed into a smaller size.

[Razor12911]

I have found a way of splitting freearc archives but at this point, it needs development before it is brought to light.

[felice2011]

I worked a short time, and the program 'complete, all automatically, except to do some copy and paste ...
1) Splits the root folder "Logically, you can not split a single large file in the folder of the game, in two or more parts"
2) Finalize the folder split by eliminating duplicate files
3) Maximum compression, with a choice from a minimum of 1 * .bin to a maximum of 8 data file * .bin.
If I can not and I have to work tomorrow I will post in the first page.

my method is very diferent. very imprecise about size, but if you want part this bat file give you parts. MULTIPART.7z

nice methods guys. I just figured a way of creating a tool for all of these issues, using your ideas of course, to ensure equal splits and max compression as well, with Precomp Srep LZMA. TBA 2015

I like both methods, these guys are good

I explained in detail this error: ERROR general (de) compression error in precomp.
The strange thing that on some folders the error occurs and no other, are forced to use the algorithm "-msrep + delta + lzma: a1: mfbt4: d158m: fb273: mc1000: LC8" that works on all folders of the games.
The algorithm: "-mprecomp +srep + delta + lzma: a1: mfbt4: d158m: fb273: mc1000: LC8" only works on some folders of games, on the other gives me the error ...
Which major differences between the two compressions?

[Dante1995]

SREP uses the first and the second also precompress ..
however precompress 0:43, I use it for my friends, and so far has succeeded in his work compiacendoli ... and use this precomp SREP + + lzma: 69mb: normal: bt4: 128: LC8


la prima usa srep e la seconda anche il precompress..
comunque il precompress 0.43, io lo uso per i miei amici, e fino ad adesso è riuscito nel suo lavoro compiacendoli, anche nei games più ostinati... ed uso questo algoritmo:

precomp+srep+lzma:69mb:normal:bt4:128:lc8

o

-mrep:263mb+srep+exe+delta+lzma:150mb:normal:bt4:128

o

arc a -w.\ -s; -ep1 -di -i2 -r -mlzma:a1:mfbt4:d512m:fb273:mc99999999:lc8

Example PayDay2 only arc = 100% precomp+srep+msc+lzma = 60%

[felice2011]

Which has the best compression ratio ???
Delle tre quale ha il miglior rapporto di compressione?????
con quale ti trovi meglio???

[Dante1995]

-mrep:263mb+srep+exe+delta+lzma:150mb:normal:bt4:128

il precompress no lo uso quasi mai, è lento e impreciso.. se devo comprimere alla grande, ricampiono i bik e l'audio wave


the precompress not hardly ever use it, it is slow and inaccurate .. if I have to compress the large, resample the bik and sound wave

[Razor12911]

felice, precomp cannot precompress some files because of the nature/stream of the file, some files has damaged or unreadable streams therefore it is either precomp freezes or it stops working then that error will show up. this errors can be fixed by the improvements of ptecomp versions like Dante said, using precomp 043 but a common trait is the fact that 042 freezes a lot therefore you can earlier versions if 043 fails as well. like 038 and 040, either way, yiu can still force precomp to work if you grab folders or files at a time till you figure out which one causes the error then apply precomp on the other set of folders and files that don't cause the error and apply compression without precomp on them.
compression ratio and best compression doesn't exist because it depends on what a compressor compresses best on a set of files.
a perfect combination of compressors such as this method precomp srep lzma. for example, there can be a best mp3 compressor but if you use it on non-mp3 files it won't work. in other words you cannot expect results everytime you use precomp or any other compressor where they will never work.

Great, I was especially interested to compile a universal software, compatible with most of the games...

Thanks I understood how it works..

unfortunately precomp is at the experimental stage, and would not recommend using it, just to recover some mb, and only 20% of the games (Srep whole life in short)

1) FreeArc + Srep are the best combination
2) Resample the video, in many games brings a huge recovery of GB
3) In games with very Audio, Resampling with PakedMSC or WaveInjection+oggenc2 is good auspicious
