A while ago, Microsoft confirmed that it’s working on a
universal app version of File Explorer and it’s not supposed to
replace the legacy File Explorer, at least for now. The new and
modern File Explorer version is actually available on devices
with Windows 10 Creators Update and newer but it’s hidden.
Microsoft hasn’t made the new UWP File Explorer widely
available in Windows 10 because it’s not ready and the project
is still a work in progress.
The UWP File Explorer in Windows 10 Redstone 5 comes with some
noticeable changes over the previous versions. First and
foremost, Microsoft has moved the toolbar from the bottom of
the screen to the top.
There’s a new “paste” option on the toolbar that lets
you paste a copied file in a folder. For example, to paste
a file in a folder, you can simply right-click any file, copy
it and finally tap on new paste option present in the toolbar.
As you can see in the screenshot above, Microsoft has replaced
the “move to” and “copy to” options with “cut” and “copy”.
There’s also a new option “set as background” that allows you
to set any picture as the background of your
desktop. There’s also a touch of acrylic and shadow
effect on the context menu.
