Hello,

possible is add to method for select DEFLATE and DEFLATE64 in 7z?
If I use command "a -t7z -m0=DEFLATE -mmt=on -mqs=on", then is working good, but not possible use in SFX (like is BZip2 in 7z)

Thanks

    I use the commands over the console.

    '/home/..../PEAZIP.Qt5/res/7z/7z' a -t7z -m0=Deflate -mmt=2 -mx9 -mpass=3 -ms=16m -mqs=on -sccUTF-8 -bb0 -bse0 -bsp2

    and

    '/home/..../PEAZIP.Qt5/res/7z/7z' a -t7z -m0=Deflate64 -mmt=2 -mx9 -mpass=3 -ms=16m -mqs=on -sccUTF-8 -bb0 -bse0 -bsp2

    The advantage over ZIP compression are solid blocks. Here in the example: 16 megabytes (-ms=16m).

    7-ZIP Zstandard Edition has a drop-down list for 7z deflate and deflate64.

    I miss a selection of the 7Z deflate (+64 deflate) compression as the drop-down list. I use PeaZip under Linux. An integration (Dropdown list) would be great.

    Thank you for integrating XZ and ZSTD in ZIP archives in version 8.2.0.

    Thank you for the feedback, I'll try to add Deflate / Deflate64 selection to the Linux GUI.

    Deflate and Deflate64 algorithms are now available for 7z format (in Advanced tab).
