Answer to aswadd use zcm 093 ...download it from encode.ru..

Best direct compressor....
1)zcm 093
2)7z
3)fazip lzma

I m not using nz

My arc setting is

Packcmd = zcm -s -r -m8 ...... ....... that all arc pack. arcdata
Unpack. = zcm x ....

LOL man i know that I got it work but decompression always failed with error 1

[External compressor:zcm]
packcmd = zcmx64 a -t2 -v -s -m8 $$arcpackedfile$$.tmp $$arcdatafile$$.tmp
unpackcmd = zcmx64 x -t2 $$arcpackedfile$$.tmp $$arcdatafile$$.tmp

@Aswadd I discussed directly with Nania Francesco on "encode.ru" and has failed to provide a solution yet, so for now it is useless to waste time.

dont use task switch
cut off the line -t2 make it like this
packcmd = zcmx64 a -v -s -m8 $$arcpackedfile$$.tmp $$arcdatafile$$.tmp

i told you it's not working multithread with freearc and inno

i tried everything :D Even using no task :] & the problem is not in compressing my problem in decompression :D If you tested decompression & was success pls type the full arc.ini for zcm pack cmd & unpackcmd
