How Can I Safely Delete a RoboHelp 9 Project?

Question

I am learning/evaluating RoboHelp 9 using IconLogic's "Essentials of Adobe RoboHelp 9 HTML".  This book  has excellent step-by-step lessons and contains student data files to make it easier to learn.  The student lessons were downloaded and unzipped into a folder called "RoboHelp9Data".  Beneath this folder is a folder named "RoboHelpProjects".  (Note there is no space in the folder name.)  At some point, I inadvertently created a folder called "RoboHelp Projects".  (Note the space in the folder name.)  As lessons progressed, I learned (1.) it is best not to have pathnames with spaces as this can cause problems on some operating systems; and (2.) you should not delete any RoboHelp files via Windows Explorer.  Rather, you should always delete them from within the RoboHelp application itself.  (Let it be duly noted that the admonition in Item 2 came with no instructions on how to do that which it admonished!)
Because I now have two folders with similar names ("RoboHelpProjects" and RoboHelp Projects"), it is causing me problems.  At first glance, it seems the simplest solution would be to remove and recreate the entire root folder, "RoboHelp9Data " via Windows Explorer.  (I don't care about losing project data---I actually want to start over.)  The thing that stops me from doing this is the admonition in item 2 above.  So would RoboHelp still be unhappy if I were to remove the entire root project folder and everything it it (via Windows Explorer).  It seems logical to me that if all traces of all project files were to disappear (including the files that contain references to the project), RoboHelp would not have anything to complain about!  (I guess that all depends upon where and how the RoboHelp application stores data about each project, and sadly, I am ignorant of that knowledge.)
As I am unwilling to stand accused by the RoboHelp application of high crimes against project data, I decided to play it safe and delete my projects from within RoboHelp and then recreate them.  It sounds reasonable, does it not?  One would think that finding out how to delete a project from within RoboHelp would be simple enough.  However, one would be wrong.
I have tried the obvious:  (1.) Searched the index and TOC of my book for info on deleting a project---no help there; (2.)  Looked for a "delete project" option in the Manager Pod "File" menu (also tried the right-click options)---no help there; and (3.) I searched the web and Adobe forums for "Delete RoboHelp 9 Project" with no success.  I did find an article about removing unused project files (Tools > Reports > Unused Files), but nothing about deleting an entire project.
As a new RoboHelp user, what I need are some simple step-by-step instructions on how to safely delete a RoboHelp 9 project from within RoboHelp.  This seems like it should be a short, simple, straightforward answer that is easy to find on the Web.  What am I missing?

Answer 1

Kevin is suggesting that you store the projects you create while working through his book in a folder called RoboHelpProjects. It is not where you have to store every project you ever create.That is for the purposes of his book.
RoboHelp initially defaults to My RoboHelp Projects but it's up to you whether you do. Generally on the forums we advise against that as  it is part of your profile and can result in excessively long path names in a few cases. Generally where authors create file names that are so long they almost serve as the content.
Projects always have a root folder, call them Project 1 and Project 2 for this purpose. You can have those folders directly off your C drive (or other local partition) or within in a parent folder as above.
Now to what you can and cannot do. You can delete a whole project by selecting Project 1 or Project 2 in Windows Explorer. Obviously if you delete the parent folder you will delete all your projects within.
What you must not do is delete individual files within a project using Windows Explorer, for that you use RoboHelp's Project Manager. The exception is if you go to Tools > Reports there is a report Unused Files. Files listed there will have to be deleted using Windows Explorer for the very good reason they do not appear in Project Manager and, therefore, cannot be deleted that way.
If you think about it, it is similar to Word. There is no option to delete a document there other than using File > Open and right clicking. Not very intuitive.
