The new File Explorer section is included as part of the Windows 11 Preview Build 22635.3640, available through the Beta Channel of the Windows Insider Program. Even if you install this preview build, the feature is disabled by default and has to be enabled using ViveTools, an open-source software that allows you to test out experimental features.
The addition of this new section to File Explorer was discovered and shared by X user and occasional Windows leaker @PhantomOfEarth who described their experience of the upgrades that Microsoft is toying with introducing for File Explorer, including ‘fancy visuals’ for sections (even if they are empty) and the introduction of the ‘Shared’ section.
File Explorer’s Home page will be getting some updates soon! The way sections appear is being updated (complete with fancy visuals if there is nothing in them) and a new “Shared” section is being added. (disabled by default, Beta 22635.3640.) pic.twitter.com/kamy1T4sSNMay 17, 2024
The first of these discoveries indicates that Microsoft is currently testing changes to the File Explorer user interface (UI), specifically three sections appearing in a sort of horizontal ribbon layout below your file folders: ‘Recent,’ ‘Favorites,’ and ‘Shared.’ Formerly (well, currently, for those of us not using a preview build of Windows 11), these appeared in a vertical list below your file folders.
