are you using zstd 32bit or 64bit in isdone ?
if you using zstd 64bit you can't decompress using zstd 32 you need to use zstd 64bit

no matters.
thanks again !

How crysis 3 pak files can be decompressed using xdelta...

[Viper645]

Any way to completely disable external compression in freearc? I mean making it impossible to enable by arc.ini or something else.

Dont know ,but if u r trying to repack it.... You cant do that ,because it uses an asymmetric cypher. (AFAIK)

so i tried to use fazip for lzma to get better ratio the limit in freearc lzma:a1:mfbt4:d185m:fb273:mc10000:lc8 using fazip i mange up lzma:a1:mfbt4:d756m:fb273:mc10000:lc8 work with ISDONE more than d756mb IT SAY NOT not enough memory...
but it is so slow compare to 4x4:lzma:64 or zstd
so ratio vs speed.
is there a way to get better ratio with zstd
[External compressor:zstd]
header = 0
packcmd = zstd -22 --ultra <stdin> <stdout>
*can i improve compression more than this setting with zstd ?
any ideas ??

[shazzla]

Maybe delta can improve compression a little bit...Give it a shot :

arc.exe a -msrep:a8:m5f:l64+delta+zstd 1.arc 1.dat

Precomp 0.38 vs 0.4 vs 0.42

Precomp 0.45, and one which is in currently in development is even better, uses only 2 temp file per stream
