Although there are a lot of ways you can use to make a zip file on your computer, I'm going to give the simplest one, as I understand that is what you would like to know. The first thing you will need to do is to create a new folder and save it with anything you want. After you have successfully created a new folder, paste all the files you want to zip into that folder.
Once this is done, you will need to right-click on the new folder you have created. You will see different options from the menu that will be displayed, just hover the cursor straight to the "send to option" and click on it. Immediately you do this; you should see a submenu with different options as well.
Hover the cursor to the “Compressed (zipped) folder” and select it. At this point, you may need to exercise a little patience if the files you are archiving are big because it might take a few minutes before the compressed folder will be created.
