Microsoft has announced Windows Insider build 17618 that adds a feature the software giant calls ‘Sets’. With the feature it’s possible to group together several applications, web pages, documents and files in a single windows and to work with them in tabs.
You could intstall this from the Microsoft store (assuming you’re one of the three humans on earth who actually uses the store), or you can just install Explorer++. Eplorer++ is FOSS, and therefore trustworthy.
