Tips

Srep Ultra Config (Best Ratio and Slow Speed)

[External compressor:srep]
;options  = l%d (minimal match length, default=512)
header = 0
packcmd   = srep64 -m5f -a1 -l128 $$arcdatafile$$.tmp $$arcpackedfile$$.tmp
unpackcmd = srep -d $$arcpackedfile$$.tmp $$arcdatafile$$.tmp

pZLib Best Config (Without Problems and CRC Error)

[External compressor:precomp]
header = 0
packcmd = pZLib e -m2 -t25p - -o - $$arcdatafile$$.tmp -o - <stdout> 
unpackcmd = pZLib d -t100p - -o - <stdin> <stdout>
