The application used to open some filetypes is 'hard-wired'. Users are not offered option to select the application 'to open with'. For example, images can only be opened in MS Paint when opened from Box on Web.

Box should either A) offer the option to select an application to open with (for applications where viewer shows content, or B) should refer to the PC/laptop's Settings\Default apps and use that application

For example, Box displays a preview of an image (jpg/png) selected, but when Open button selected, only MS Paint is offered to open the file. The world has moved on since MS Paint..... the default application for images should better be MS Photos if installed, which Microsoft says is "seamlessly woven into the fabric of Windows 11"

But, ideally, for any application that Box is able to preview, it should be possible to open the file in the application that is set as default in Windows Settings
