I want to export files to a flash drive on my iPad. There are several flash drives that have both lightning and usb plugs but I don't know if Affinity will recognize any of them. If I can't export directly is there a roundabout way, exporting to another application and then to the flash drive. I need to export jpg but would also like to export psd or raw. I'm looking for brand names of flash drives that work with Affinity.
