Rendering Directly to File

nonesuch00

OK, because my last attempt to render crashed at 75% and 2 days render time I decided to render a png directly to file. However after 25 hours & 51% completion their is no temp render file in my

<System Drive>:\Users\<User>\AppData\Roaming\DAZ 3D\Studio4\temp

directory and the file that I told DAZ Studio to render to, remains only 15.8 kb in size.

Is this render still completely in RAM even after a day of rendering?

I would like to copy the temp file to ask opinions about if the lighting needs adjustment again before it goes another day or two rendering.
