If you’re like most people, you probably open files on your iPhone using the built-in file manager, such as Finder or iFile. But if you want to open files in a more specialized application, there are a few ways to do it. The first way is to use the “Open with” command in Finder. This will open the file in the application that was specified by the “Open with” command. The second way is to use the “Open with iTunes” command. This will open the file in iTunes if it’s not already opened. The third way is to use the “Open with AirDrop.” This will open the file in AirDrop if it’s not already opened.
