![]() I did however compress encrypted files from AxCrypt at again 30% smaller. I can give it a try for for amusement and maybe it will hit 1% smaller if not have negative gains. I have not attempted to re-compress the output files as I do not expect any type of serious gains. With precomp I tried a few various other settings to optimize and ran it to compress it down to ~30% >~30% LESS NOT DOWN TO ~30%> was added after the post by me for clarity on March 19th 1pm ish EST Specifically used enwik8.rar and enwik8.zip and ran precomp048dev.exe default and precomp048dev.exe with -intense to create the pcf files for compression.
