My client made a small change to a text element in an Edge Animation. I changed the .oam extension to .zip and extracted. I made the change to the .svg file and rezipped the files and changed the extension from .zip back to .oam. However, this dis not import back in to InDesign. In fact, when I look at the file-type, it still says "zip file" and not "Edge Widget file" despite my reassigning it to be a .oam.
Any ideas how I can make the .zip file (which I renamed to .oam) into an importable .oam file?
