Magewell USB Fusion HDMI & USB Video Capture Device - Manual (Page 59)

On iOS devices, resources imported to the USB Fusion are also
saved in the App. When importing a file to the USB Fusion
device, importing from the App is faster than importing from
the iOS system or other locations, especially for large files. If
you need to delete a resource, long-press the resource and tap
the delete button.
Locations : non-local pictures that can be accessed by the iOS system,
including files on cloud storage (such as Box, Dropbox), file servers and
connected devices (such as USB flash drives and SD cards). The
following describes how to access cloud storage. For methods to
access other locations, see Apple Website .
When importing files from cloud storage, tap Browse (at the top or
bottom, depending on the iOS version), and tap a cloud storage app
under Locations to select a file.

If you import from Cloud Drive, you need to first enable iCloud
Drive. For details, see How to import a resource from iCloud Drive .
If you import from other cloud storage, you need to first install and
log in to the cloud storage app. The operations to access different
cloud storage services are similar. For details, see How to import a
resource from Google Drive .
Only the cloud storage apps that allow the system to manage
will be displayed under Locations . If a cloud storage app
does not grant the management right to the File App, you
cannot import files from the cloud storage using this method.
