Here are a few ways you can use folders in Gmail:

2. Move emails to a folder: Select the emails you want to move to a folder by checking the boxes next to them. Then, click on the "More" menu and select "Move to" and then the name of the folder you want to move them to.
3. Use labels: Gmail also uses labels instead of folders. You can create a new label by clicking on the gear icon, then selecting "See all settings," and then scrolling down to the "Filters and Blocked Addresses" tab. Click on "Create a new filter" and enter a name for your label. You can then apply the label to emails by checking the box next to them and clicking on the "More" menu and selecting "Apply label."
4. Use the "Move to" feature: You can also use the "Move to" feature to move emails to a folder. To do this, select the emails you want to move, then click on the "More" menu and select "Move to." Then, select the folder you want to move them to from the dropdown menu.

As for the "clear legal size flap folders" part, I'm assuming you're referring to a physical folder that you can use to organize your papers and documents. If that's the case, you can use a folder with a clear plastic window to view the contents without having to open it. These types of folders are commonly used in offices and are often referred to as "flap folders" or "file folders."
