If you have a Chromebook, you may find that unzipping files isn’t as simple as right-clicking on a zip file and choosing Extract All, which is how it’s done in Windows.
It seems that when you double-click on a zip file on a chromebook, the zip file is treated like an external drive, as it appears to “mount” the zip file like a drive on your system. You can then see the contents, and copy/paste the contents of the zip file to another folder.
