So far I've not come across a simulator which cared about the extension. 
  But I'm not an LTspice user.


BTW, why LTspice and not ng-spice or gnucap which are both open source? 
  With either of them, you can avoid tying yourself to a particular OS, 
they both have mailing lists with not just users but program developers, 
and you have more of an ability to influence the tools.

I've been down the path of closed source software with cheap or zero 
cost to obtain before and at the end wished I hadn't.  The particular 
nameless tool ended up being a dead end road since I ultimately needed 
to migrate to another OS and didn't want to shell out thousands for 
something I was using as a hobby.

Just my 2 cents.
