Thank you for your response, Bulat.

It's great to see the initiator himself is present among us.
I have obtained the xz and lz77 32Bit variants through googling.
However, the problems I have are the following.
Code:
[External compressor:xz]
header = 0
packcmd = xz a -txz -an -mcrc=0 -m1=lzma2:d25:fb=273:mf=bt4:mc=1000000:lc=4:lp=0 -mmt=2 -mx9 -si -so <stdin> <stdout>
unpackcmd = dec x -txz -an -y -si -so <stdin> <stdout>
This is what my arc.ini looks like. And it always results in the compression process stopping whenever I am using the x86 variant of xz with the error hard disk is full. I, by no means understand the parameters used in the compression and I'd very much appreciate it if someone could point out what I am doing wrong?
