I find that having a "standard" project directory with sub-directories for all projects to be of great value.
I do not know what others have done when they start a new project, but I can tell you that I simply copy-n-paste, then rename this "template" into my ..\Projects\ directory, and then work from within the template's standardized structure.
e.g. ..\Projects\Alpha
Where "Alfa" is the renamed standardized structure.
I will add sub-directories to this standard structure when it is deemed appropriate. I highly recommend this structure to people who work on multiple projects and add this bit of advice to their methods.
