I would like to transfer all the files in a particular album from the "Files" app to the "Photos" app on my iPad. I used Airdrop from my MacBook to transfer several video and image files to my iPad. I confirmed the files were sent by viewing some of them. I'm also starting to use Kinemaster for video editing on the iPad. It looks like when I select the "Video" tab and "All" from the "Albums" section of Kinemaster, it only allows me to access albums that were created using the "Photos" app.
There was no access to anything I had in the "Files" app. That would lead me to assume that if I transferred the album of the videos and images from the "Files" app into the "Photos" app, Kinemaster will have access to them. I selected all of the images and videos in "Files" and tapped "Share", but did not see "Photos" as a target app in the list. I even tapped the "More" dots button but "Photos" was not listed as a target either.
The attached screen shots show the choices the iPad gives in the "Sharing" screen.
