Problem with ZTOOL

[Schabik]

I'm trying to compress combining pzlib or pzlib:max method with srep/SREPMAX or other and freearc just skips the beat as I can say.
ZTool compression is just skipped and freearc proceeds to next method.

Arc.ini file is presented as below:

[External compressor:pzlib]
header    = 0
default   = :max:c32m
packcmd   = ZTOOL\ZTool e:pzlib:t25p{:option} - - <stdin> <stdout>
unpackcmd = ZTOOL\ZTool d:pzlib:t100p:cm0 - - <stdin> <stdout>
datafile  = Input

I've tested also below configuration:

[External compressor:pzlib]
header    = 0
packcmd = _Compressors\ZTool e:pzlib:t25p:c128m{:option} Input <stdout>
unpackcmd = _Compressors\ZTool d:pzlib:t100p:cm0mb - - <stdin> <stdout>
datafile   = Input
