Re: Large files on Windows?

Hi Neil,

I think I grasp the high-level meaning of what you say.

From my side as a user I am happy to know that I can use right-click 
options as usual while I need to go for "File, Open" for large files.

SciTE is really great: thanks to all involved!

Thanks again

Best Regards
