Import/Export problem for .obj files in Blender 2.79 I'm using Blender 2.79. Importing and exporting .obj files worked fine. Then I uninstalled blender and reinstalled. Now I can't able to import/export .obj files. Then I tried back Blender 2.78c. No error popped up this time! -_- .

Can someone please explain?

Error:
I had similar problem. It's caused by Widnows Defender Security Center.
I solved it by opening Security Center -> Apps &amp; browser control -> Check apps and files set to off
