I have a large collection of Serif wmf files. I find them useful because I can start with a ready-made file and adapt it for my purposes. Until now I've been using the Microsoft Office 2010 facility for viewing a folder's worth of wmf files and selecting the one I want. I've had to upgrade Office and they don't seem to support this any more. How do I preview wmf files before choosing which one to open in Affinity Designer?
