Won't Open a WMF...that's true.
Use File | Place to import it into an existing document.
Unclear, I have just started using InDesign and am taking an online class. Please explain.
I just tried file then place and I see it worked. The class I am taking is for CS 5 and I see there is a difference. Thanks!
You should not use a WMF file anyway in InDesign, try to get a PDF, AI or EPS version, then place this file. WMF is supposed for office printer to use in Word or other Office programs, not for high end print production or PDF creation at all.
If you get a PDF version, don't ise any which was converted from the WMF file!
