I have crashed several times this morning while using QTO 2013. I am using DWFx files. The 3D is 900 kb, the 2D sheets are 17 mb and the QTO is 25 mb. I am using a Lenovo w520 with 8 gb RAM. I am using build 18.104.22.168 .
What is prefered for QTO 2013, DWF or DWFx files?
What file sizes cause issues?

If the project is complex, I would try the suggestions from the following help topics page on managing project size:
I also recommend turning on the “Auto Save” function so that periodically the application saves a backup of your work in case a crash occurs. This setting is found in the preferences as described here:
