Microsoft appears to be adding a tabbed interface to the top of File Explorer, as Insiders testing the latest Windows 11 preview build have discovered the feature in a hidden state.

First spotted by Windows Insider Rafael Rivera on Twitter, once enabled, tabs will appear along the top of the File Explorer app, allowing users to have multiple folders open in one window.

Tabs in File Explorer has been a highly requested feature among the Windows community for years at this point.

Microsoft almost delivered the feature via its canceled "Sets" UX, which saw the introduction of tabs in every app window, including File Explorer.
