hi,
using this designer second time and need help.
please see 3 images attached below and kindly explain how to do settings in marked sections and what are they for ?

i am using below code to compress files :-

arc a -lc8 -ep1 -ed -r -w.\ Data\data-1.bin -mprecomp+srep+lzma:a1:mfbt4:d256m:fb128:mc1000:lc8 "C:\The Evil Within\audio\*"

and below arc.ini file :-

[External compressor:srep]
;options = l%d (minimal match length, default=512)
header = 0
packcmd = srep {options} -m3f $$arcdatafile$$.tmp $$arcpackedfile$$.tmp
unpackcmd = srep -d -s $$arcpackedfile$$.tmp $$arcdatafile$$.tmp

[External compressorrecomp]
header = 0
packcmd = precomp -intense0 -c- {options} -o$$arcpackedfile$$.tmp $$arcdatafile$$.tmp
unpackcmd = precomp -o$$arcdatafile$$.tmp -r $$arcpackedfile$$.tmp

Kindly help me to upgrade my arc.ini file so that it not show that "precomp.exe has stopped working".

Please solve my all doubts. i just meed compression and extraction tutorial :'(
