Mobi output location

Sorry if this is a repeated question.
When I convert an epub book to mobi Calibre creates a dedicated folder that contains the mobi file. Is there a way to just save the mobi file into a dedicated folder? I hope you understand the question.
I move the mobi file after conversion and delete the folder. Would like all the mobi files to go into 1 folder and not have to move and delete.
thank you
