Although I'm posting this issue for Photo, it also happens in Designer.
When I drag this file to open it on Photo (or Designer) I get on top right corner of the application window "Loading 1 document..." and then noting happens.
Usually, after a short time I quit, open task manager and... you know the rest.
This time I've decided to wait and while on Google Chrome, he (Chrome) started to "freeze" and eventually throwing memory errors.
I opened task manager and Photo was consuming an insanely amount of memory and moderate CPU and Disk.
It opened the file after some 5 minutes.
This file was generated by a CAD program used to produce maps and this issue happens with any other file that comes from it.
It opens in Photoshop or Illustrator with no issues.
As for now I can't disclosure this file in public so could you provide-me a dropbox link to upload it?
