Large Files ipad backup
My iPad's backup has a huge 17GB backup of Files, as seen in the screenshot below taken from Settings → My Name → iCloud → Manage Storage → Backups → My iPad
I would like to reduce the backup size of Files, but when I launch Files, there's no column for file or folder size, so it's difficult to see why backing up Files is so huge.
Any advice on how to weed out the huge Files folder/file?
Thank you.
