3. From there navigate to the file, and then press and hold on the file to bring up the menu.
4. Select the Copy or Move option
5. Navigate to the location you wish to save it on your iPhone in the Files App.
6. If you chose Copy, press and hold on an empty area of the Files App, and then select Paste.
7. If you chose Move, it will open a window for you to navigate to a location to save the file, tap on "Copy" on the top right corner to copy the file to the location. (Despite its name, it will not actually move the file, only copy it).
