Here, we share methods not conceil it, this thread is ment to provide info, how to achieve this size. I tried to contact hime but he didnt responded.
I tried to use dlc extractor and xdelta to make it work but after comparing (recreated .sfar )files with orginal, xdelta produces orginal size patch which is useless. if anyone know how to do this let me know.
My theory about how (i guess is his doofoo) compressed it from 24.3gb to 8gb is he extracted .Sfar files and then recreated .sFar from extracted content without useing lzma compression (hence the game size 24.3gb).
Cp has also compressed mE3 from 16.5gb to 11.5gb (compression ratio of around 70%) which is same as mine that means they have encoded videos.
My orginal game size was 24gb after removing French, Italian and German languages, it came down to 19.2 (with single int(english) language)

.SFAR files used in Mass Effect 3 uses LZMA compression. Normally it is a very very stupid idea to do precompression of LZMA because you know its going to be very slow unless you have a proper way of doing it in MT. To match the data/size with originals so that you dont get large xdelta patches, you have to match the LZMA parameters,block size etc... as it was used in the originals.

And for Shelwien's tool, you are confusing plzma. He has also created a lzma recompressor with no internal compression so that you can apply further compression but its very very slow and for advanced users.

^^He is right, LZMA is slow AF, you can use lzmadump for recompressing them, but it's a tool like old reflate, and very much slow.

Sry cant check, I can only count to 100 lol, nah I am just too sleepy to do so!!

i have more just waiting to see what razor does with xtool
i hope he adds vp6

[doofoo24]

pzlib:m2:c16m+srep:m3f:a2+lolz:d64 size 4.01gb to 1.05gb english only...

[kassane]

I tested quickly using this combination:

srep:m5f:l128:a1+lolz:mtt1:mt4:fba2:mc2:cm1

Original Size: 32GB
Final Size: 23.4GB

Two languages : english and spanish only

[doofoo24]

ztool:plz4+srep:m3f:a2+lolz:d64m english only

[doofoo24]

ztool:plz4+srep:m3f:a2+lolz:d64 all loc+mp

[ZakirAhmad]

used xtool + srep+ lolz on zlib files.
bpk + srep on bik files.
srep+ lz77 on sound files (as always oggre failes on them)
srep+ lolz on bin + bundle files
and srep + exe +delta +lolz on rest files.
xtool improves compression around 200mb than pzlib. xtool version is v03.

All creadit goes to Razor.
Extaction time reduced by 14minutes.
FGs version took 44minutes while mine without binkpack took 28minutes, that adds only 2 minutes for bik videos.

[doofoo24]

precomp:c32mb,t100p:lz4+srep:m3f:a2+lolz:d64 from 27.gb
*use xtool

[doofoo24]

precomp:c32mb,t100p:lz4+srep:m3f:a2+lolz:d64 from 23.7gb sp only with en without mp/xp filles...
*use xtool

batman arkham knight premium edition

26.2 gb new size

previous repack size

27.4

previous compression method was removed due to the quality
and the decompression speed differences

Compression Time?

time on compression to me does not matter to me besides i did not keep track
i was at work while it repacked and my compressor does 3 data files
it only showed the timeframe for the final file
decompression takes around 30 minutes though
previous method with lzma took around an hour and a half
to decompress
