File Explorer - Now has Tabs
Just like we can open tabs in a web browser, File Explorer also lets you open or add new tabs. So, instead of opening multiple File Explorer windows, you can use tabs to open different folders, drives, etc., to ease your work. For this, you can use any of these three methods:
Click on the Add icon (or plus icon) available just next to a tab in File Explorer.
Use Ctrl+T hotkey.
Right-click on a folder or drive and use the Open in new tab option. A new tab will open immediately with that particular folder or drive. This option won’t be available when you have selected multiple tabs.
