Deleting Project Files

Borge. . . Well you caught me flat-footed. I didn't actively save any of 
the project files. They went wherever Quanta put them. I assume that 
they are automatically saved under a Quanta directory which I've tried 
searching but haven't found a specific project file list that I felt I 
could delete. I went through this a year or so ago, and as I recall I 
was directed to follow a path to where the project files were listed and 
where I could delete them.
