Extraction script running correctly but very slowly

[troyosaurusrex]

So, I am very new to programming still! This was my first time installing a package and running it in a virtual environment. I have a bunch of .7z files in my downloads folder that are relatively large, anywhere from 300 mb to 3 gigs. I want to extract them and move the extracted files to my Romtest folder. This is working just fine but I find that each file is taking a minute or longer. It's still saving me clicks so it's not a huge deal, but I would like to know what I'm doing wrong. Any responses are appreciated. I'm also executing the file inside VS Code if that makes a difference.

I only have about 100 files in the downloads folder. Inside each zip, there are 1-3 files. Total size of contents comes out to maybe 20% bigger than the zip file.

I'm so noob I can't even format my code properly when pasting it. Here is a pastebin: https://pastebin.com/J8dzaJdC

Environment:

OS: Ubuntu 22.0.4 LTS
Python 3.12.3
py7zr version: 0.21.0

I think I found the answer. I needed to import multiprocessing. Thank you new Claude 3.5, thanks for nothing ChatGPT.
