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

Successfully unpacked zstd 64 bit archives with x86 version.




Many-many thanks...
its working fine now !
I dont know what caused the error ,but its fine now!
im a little bit confused ,because the compression-syntax is pretty easy ,but...... :D
no matters. :)
thanks again !

Where I can I get freearc .70 to download ?

correct question is "When". answer is never, i plan to release 1.0

And when 1.0 ??

And how can I optimize cpu and time both ?????

But your site still shows .70 will arrive in Feb still ?? Hahha

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

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 ??

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

Which is better?
Precomp 0.38 vs 0.4 vs 0.42

Which is better?
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
