To delete a folder, first select the folder name you want to delete then:

 

 From the menu select Project -> Delete

or

 Right-click and then select Delete

 

You will then be prompted to confirm your delete action.  Once you confirm that you want to delete the folder, the folder will then be deleted.  This action cannot be undone.

 

If you have any evaluation projects in the folder you will not be allowed to delete it.  You will need to delete the individual projects first and then delete the folder when it is empty.
