Batch repacking archives into 7z with custom settings

Question

I'm working on archiving and compressing a lot of design elements and they are mixed in .zip and .rar files.

After tinkering and testing these settings seem to produce the best results for me:

I'm following this nice piece of code posted in this question and I'm trying to modify it to have the settings I want.

However, the .bat will not run.

This is the code I have:

for %%F in (*.rar) do ( "C:\Program Files\7-Zip\7z.exe" x -y -o"%%F_tmp" "%%F" * & pushd %%F_tmp & "C:\Program Files\7-Zip\7z.exe" a -y -r -t7z -m0=lzma2 -mx=9 -mfb=128 -md=512m -mmt:on ..\"%%~nF".7z * & popd & rmdir /s /q "%%F_tmp" )

---

Additionally is there a way to have this run on BOTH .zip and .rar out of the same .bat? Right now I have 2 versions.

Answer 1

The -mnt:on option is simply wrong, at least with my 7-Zip 18.05 (x64)

This batch:

:: Q:\Test\2018\10\11\SU_1365974.cmd
@Echo off
Set  z7="C:\Program Files\7-Zip\7z.exe"
Set "z7o=a -y -r -t7z -m0=lzma2 -mx=9 -mfb=128 -md=512m "

for %%F in (*.rar *.zip) do ( 
  %z7% x -y -o"%%F_tmp" "%%F" *
  pushd %%F_tmp
  %z7% %z7o% ..\"%%~nF".7z * ||(pause)
  popd 
  rmdir /s /q "%%F_tmp"
  Rem del "%%F"
)

(remove the Rem in front of del to delete the original archive file)
Produced these results on sample zip files mostly from an arduino installation.
