When working with zip files Mac and PC users have different options. Learn how to use zip files in Windows 10 and on a Mac here.
Windows treats zip files just like folders. You can open a zip file, move files in and out of it, and open individual files just like you would if they were in a folder.
Accessing the contents of a zip file
Because Windows makes it easy to work with zip files, there's generally no need to unzip them. However, if you would prefer to unzip them you can simply right-click the zip file's icon and select Extract All.
Opening a zip file in OS X is slightly different from Windows. Instead of opening the zip file directly, it will unzip the files and place them in a new folder. You can then open the folder to access individual files.
