How do I enable multi-threaded LZMA2 using 7-zip 9.20 on the command line? I know this is normally done with the -t option like so: "-tzip" .
How do I do this with LZMA2? I tried -tlzma and -tlzma2 and neither one works. I also tried not passing -t at all, and it just runs single threaded with "lzma" mode.
Here is the command I currently have, but it is slow, and single threaded:
"C:\Program Files\7-Zip\7z.exe" a -r -tzip -y XMLBackup.zip *.xml
