Some of the folders in my Gmail account disappeared. The Spam folder was one of the folders that were gone. I could still click the More link to access it, but this was annoying. I wanted my Spam folder back. I located a setting where you can control which folders are displayed on the left menu of Gmail. I suppose this is a good setting for reducing clutter if you’re a person who likes to use a lot of email labels. Here’s how to show or hide folders.
1. Login to Gmail.
2. In the upper-right corner, click the gear and select Settings.
3. Click the Labels tab.
4. Click the Show or Hide link next to the folder you wish to show or hide. In this example, I am choosing the show the Spam folder.
