I'm currently using the following:

       Active ³ Yes
    Extension ³ ZIP
           OS ³ Linux
  Description ³ Info-ZIP Utilities
     Pack Cmd ³ zip -qj9 "%1" %2
   Unpack Cmd ³ unzip -oqqjC "%1" "%2" -d "%3"
     View Cmd ³

(Notice the "%1" and "%3" but %2; speaking of quoting or not quoting "%3".)

It seems to be working just fine.

From the (built-in) archive viewer, I could navigate inside a ZIP containing a subdirectory and some files, and it viewed (= unpacked and displayed) them just fine.

An strace looks fine as well:

write(17, "2021.08.05 22:22:14 Executing: unzip -oqqjC \"/mnt/bbs/mystic/files/local/uploads/test.zip\" \"subdir/test2.txt\" -d \"/home/bbs/mystic/temp2/\" > /dev/null 2>&1\n", 156) = 156
close(17)                               = 0
fork(strace: Process 2298 attached
)                                  = 2298
[pid  2298] execve("/bin/sh", ["/bin/sh", "-c", "unzip -oqqjC \"/mnt/bbs/mystic/files/local/uploads/test.zip\" \"subdir/test2.txt\" -d \"/home/bbs/mystic/temp2/\" > /dev/null 2>&1"], ["LANG=en_US.UTF-8", 

Best regards
