SMB is a network file sharing protocol that allows an application (or the user of an app) to access files or resources at a remote server. We’ll show you how to access files from your Mac or Windows 10 computer directly through the Files app on your iPad. You can view documents, play audio or video, markup PDFs, move and copy files, and much more. It lets you access large files, which helps you save space on the device. The SMB (Server Message Block) network protocol integration in iPadOS was a game-changer because of its benefits.
The Files app is a kind of central repository that allows you to work with the files stored on your iPad, network servers, and cloud storage services.
