When testing it shows this error

It worked once and showed a good ratio

It worked once and showed a good ratio

use mtx to split it into chunks,im guessing its a stack overflow error (based on my prior attempts at rectification),fastlz is 32bit (ithink) meaing i will have to try and port it to 64 bit

also by very good ratio,the output data is likely corrupt

[soulfit15]

btw the error appears when specifying a temp directory actually using -w.\tmp
will try MTX however
thanks

could you also send the input data you used so i can try to rectify the errorlevel

i used this in plain arc arc a bin01.bin "folderpath" -mfstlz -w.\tmp

tried it in MTX 5.0.0.1 keep getting disk size error (which is strange although i made sure that the arc.ini was good.

in MTX 2.0.0.1 however
arc a bin01.bin "folder" -mmtx:c128m:t4:fstlz -w.\tmp

this showed great results near lolz on my tests actually

,can you tell me how to mtx 2.0.0.1 step by step

[soulfit15]

1) copy 6pack.exe into "cls-mtx v2.0.0.7\Compressor\Bin"

2) added arc.ini lines [External compressor:fstlz]
packcmd=6pack.exe -2 $$arcdatafile$$.tmp $$arcpackedfile$$.tmp
unpackcmd=6unpack.exe $$arcpackedfile$$.tmp

3)used the command
arc a bin001.bin "folder" -mmtx:fstlz

another report, I got it to work with MTX 5.0.0.1 but I don't know where is the problem. it showed a worse compression ratio

im guessing its a bit limit (the exe is a 32bit exe and not 64,so my guess it needs to be ported to 64 bit),and the worse compression ratio is likely correct,but i would test decompression to see if it compressed it correctly

working on my own 64-bit (though simpiler) impimentation of the fastlz compression libary (to fix it)(and Done

Compression ratio difference those 6/7pack compressors compare than FLZMA2 or ZSTD or any codec??

^^
Why don't you benchmark them and let us know? :p
