[Tutorial]Use the archive tool to uncompile *.arz and *.arc

Would anyone know how to re-compact folder into an archive? I thought it would be intuitive once I finally figured out the extraction.

Basically i’m typing:

File/path/to/folder -add file/path/to/directory/where/archive/will/go (thefolder name) and 9

9 is for the compression settings? I probably typed the damn command WAY wrong, but I was trying to copy the instructions listed in cmd by the archivetool itself.
