According to a screenshot (via Bleeping Computer), the advertisement appears above the folder listing and below the address bar. In the screenshot, the message reads: “Write with confidence across documents, email, and the web with advanced writing suggestions from Microsoft Editor” with a “Learn more” button that opens the web browser to the Microsoft 365 website. Of course, the new attempt from the company to push its products was not well received since most people would agree that showing ads in File Explorer is among the worst places. This is not the first time Microsoft has tried to put ads in the default file manager. In the past, the company has shown an advertisement to lure users into using OneDrive. Also, the company has tested a similar approach to push its Office web apps in the WordPad app. Another example is the recommendation to use Microsoft Edge when searching for Google Chrome or another browser in the Start menu. Update March 15, 2022: Microsoft has said that ads in File Explorer found in build 22572 were not supposed to be seen externally, and the app will continue to be available without advertisements. In a comment to The Verge, senior program manager for Windows, Brandon LeBlanc, said that “this was an experimental banner that was not intended to be published externally and was turned off. However, it’s clear that the company is capable of showing advertisements, and the statement doesn’t rule out that at one point the default file manager may someday start showing ads.
