To get a .ZIP or .7z file, it really will do one of two things: ask you in which you want to save it on your PC, Laptop, or save onto a default directory, like your Downloads folder.

You can decide exactly where it has saved to by going to the window with the all of the saved files in your browser (such as Google Chrome, Mozilla Firefox, Safari,…). Just right-click on the folder, and select “Open Containing Folder” or “Show in Folder.”

When you need to use a file inside the .ZIP or .7z file, you will need to extract those files before launching. You may do this by right-clicking the .ZIP or .7z file, and click on “Extract here” or “Extract files to …”.

That will then open up a Windows Explorer program default in which you may select the place you need the files to be uncompressed too.

I would recommend getting a new folder in that directory, and then double-click on it and extracting the files here.
