Watch how much the 7z.exe weighs (I mean space. It'll be 1.09MB likely for 64bit one. 720KB likely for 32 bit one)
7z.exe for xz(lzma2) isn't the same in size for general 7z patch. In 7z(for xz/lzma2) parameter -txz is used in packaging parameter not -t7z.
Also dude it's written
HTML Code:
packcmd = 7z.exe a -txz -an -m0=lzma2(:options):fb=273:mf=bt4:mc=100000000:lc=4:lp=0 -mx9 -si -so <stdin> <stdout>
Never used lzma in the place of "lzma2" in the packcmd parameter.it matters a little about what you write in [External compressor] whether it's lmza2 or xz
during compression use or u can say for compression method
HTML Code:
lzma2:d256m:mt2
(Will help you to keep the track about how much directory and multithread you had used for files.but use lzma2 in case of renaming it in External compressor)
#
d is directory and of course
mt is the thread number
#
I had encountered disk error when used "d" more than 128 for 32bit executable.just a reminder tho
That should work fine.with best regards
