Ever compressed your project directory but forgot to delete that useless file or folder and turns out the compresed file is larger than it's supposed to be?

Here's a quick solution you can try:

If you want to delete a file inside a .zip file, try this:

zip --delete file.zip "file.ext"

And if you want to delete a folder, try this:

zip --delete file.zip "folder/*"

Hope this helps you out!
