I have not had this problem with Cmd use, used individually or with FA support, awesome speed and good compression.
Code:
pzstd -u -22 -f -n 4 -p
Code:
[External compressor:pzstd]
;header = 0
packcmd = pzstd --ultra -22 -f -n 8 -p $$arcdatafile$$.tmp -o $$arcpackedfile$$.tmp
unpackcmd = pzstd -d -f -n 8 -p $$arcpackedfile$$.tmp -o $$arcdatafile$$.tmp
OK you've solved.
