Where are the converted files

Hallo, I am trying to convert an ebook into a pdf file. For testing the conversion I used the "Calibre Quick Start Guide" as ebook. THe conversion job takes few seconds and then if I click on "show details" button I get log text: the last line says:

"PDF output written to C:\Users\xxx\AppData\Local\Temp\calibre_p3kqs8\_pj vhr.pdf"

But when I open this location there are only some files with a ".pickle" extension a log file. The PDF is not there. And I also don't understand if it is possible to configure a different output location.

Thanks
