How to make the console version of 7zip unpack a file consisting of a pathname in lua?

Question

Lua

path_e = 'C:\\7-Zip\\7z.exe e '
my_file = 'C:\\test\\123.docx'
dir = 'C:\\test\\112233'
os.execute(path_e.. my_file..' -o'..dir)
In this form, everything is processed correctly.
But if you change the file name to '12 3.docx' or '1 23.docx' (i.e. the file name consists of several groups of characters or numbers), then 7zip "writes" that the archive was not found.
I ask for help in issuing a command to unpack a file of the form: "this is such a long file.docx"

Answer 1

Wrap in quotes? :)

Answer 2

Yes, it was necessary to wrap it in quotes, i.e. escape from both sides '"' my_file, thanks to ElijahTr for the direction of thought, the code below works:
os.execute(path_e.. '"' .. my_file.. '"' ..' -o'..dir)
