Simply i would like to add sum-ups here, something might be wrong because i am too lazy to update it
To Compress Unity Game Engine Created files like *.resS, *.file files
use srep + lolz
lolz = -dto0 -tt1 -dm00 -mc1023
srep = -m3f -l512 -a2
Note: for these unity game engine created files you can also use precompress to reduce the file size more
To compress again unity game engine created files *.resource, *.assets files
use srep64+lolz
srep64 = -m3f -l512
lolz = -d256mb -tt8 -mc1023
To Compress *.xxx files(Unreal Engine Files) (But cannot be compressed with uelr)
pzlib = try with defaults first, then you can play around
srep = -m3f -l256
lolz = -dto0 -tt1 -dm00 -mc1023
To Compress *.txt, *.exe, *.dll, *.ico, *.ini, etc files
use bpk+srep+dispack+lolz (bpk if their are *.bik files with these above mentioned files)
bpk = default
srep = -m3f l512
dispack = default
lolz = slow to reduce the file size or use fast one to make it a slight big but faster compression, somewhat 10X
To Compress Unreal Engine Files for e.g *.tfc, *.upk, *.umap etc etc
use uelr+srep+lolz or uelr+srep64+lolz >only 5-10kb differences when using any of em
uelr = default
srep/64 =-m3f -ia- -l512 )+
lolz = slow
Note: don't use -ia- if you are experiencing some problems when de/compressing
On compressing sound *.pck files compression was awesomely fast by using srep64+lzma:ultra(but 2mb increase in file that i used to compress) and srep/64+lzma2 than using srep64+lolz(slow compression), i think lzma is doing better in .pck files
upon using -d256mb -tt8 -mc1023 lolz settings compression speed is slow and the decompression speed is Good. but upon using -dto0 -tt1 -dm00 -mc1023 lolz settings compression speed is faster and the decompression speed is same. file size after compression using the -dto0 -tt1 -dm00 -mc1023 setting was 1kb less than using -d256 -tt8 -mc1023
upon using nz with srep64+lolz compression is slighlty top notch....its upto you guys now what to do
On compressing *.forge files with afr+srep64+lolz taken much time(headache) than using afr+srep64+lzma:ultra(fast compression but about 187mb in increase in file that i used to compress
i think for *.forge files it's good to use srep(-m3f -ia- l512) but it may differ from time to time
Note: on *.forge files if the lolz settings are -d256mb -tt8 -mc1023 then it may take hours to compress a 1 GB file(headache) and the decompression speed will be normal.
but if we use -dto0 -tt1 -dm00 -mc1023 lolz settings then the compression speed is faster as well as decompression speed also...
BTW YOU CAN TRY LOLZ SLOW ON THESE FILES ALSO AND REMOVE THE -IA- option if not needed
At last, every game engine file doesn't help you what does it uses, better to think about like this i.e check game engine > check game file extension > and play with compression then to achieve lowest size as possible + it will nurture your skills also in Data Compression
More Coming Soon, If these are helpful
