Document display in File

I've just bought the latest iPad Pro 12.9 and I'm struggling to set it up. I've got a MacMini & a MacBook Air. I've got thousands of Word documents in Finder on my MM & MBA. I don't want to use Pages so I've installed Word on my iPad. I used AirDrop to transfer some Word documents to Files on the iPad. I now have these documents in a folder in File but they are in reverse alphabetical order with 'z' 'x' 'y' at the top going down to the 'a' documents at the bottom. I know it will be something simple but I can't find the solution. How do I arrange my documents in alphabetical order as opposed to reverse alphabetical order? Many thanks for trying to help.
