File browsing is something everyone inevitably has (or wants) to do, so you might as well do it with a capable, fantastic file browser. Solid Explorer is pretty much as good as it gets in the file explorer apps realm. It features Material Design, archiving support, support for the most popular cloud services, and even some more power-user stuff like FTP, SFPT, WebDav, and SMB/CIFS support.
It looks great, it’s incredibly stable, and it just works well. There is a 14-day free trial with a $2.99 price tag at the end of it. There are other file browsers with more features, but few blend together looks, ease of use, and features like Solid Explorer does.
