Moving files from external hard drive to iPad through iMac
I'm trying to move some video files onto my iPad, as it has a lot more storage than my other devices. All of my video files are on my external hard drive. I am trying to use a 2021 iMac to liaise these files but I am struggling.
The first time I tried it, I had some trouble but I was eventually able to get my video files to show up in the 'Files' folder on my iPad. Now when I connect and try to transfer files, I keep ending up with the videos labeled as music videos and only accessible through iTunes, which is NOT what I want.
How can I get a file from an external hard drive to an iPad using an iMac WITHOUT using iCloud? How can I keep files from showing up as music videos?
