Solid Explorer
File browsing is something that everyone needs to (or wants to) do, so why not do it with a functional, great file browser? Solid Explorer is about as excellent as it gets when it comes to file explorer programs. It has Material Design, archiving support, support for the most common cloud services, and even some more advanced capabilities such as FTP, SFTP, WebDav, and SMB/CIFS compatibility.
It looks beautiful, it's really solid, and it just works. There is a 14-day free trial with a $2.99 fee at the conclusion. Other file browsers have greater functionality, but few combine appearance, simplicity of use, and features as well as Solid Explorer.
Price: Free trial / $2.99
