It is possible to move folder objects around, but products can supposedly only be cut, copied and pasted in the products directory. Could anyone give a rationale for this?
The Products Folder is a special object for, naturally, Products -- both disk-based (ala the primary built in Zope products, as well as any others) and Zope-based (Products that are instantiated using Factories). Remember that Zope Folders are not directories, but are actual objects, and some objects may act folder-ish but be very specialized and may only allow certain types of objects. (Similar to the Control Panel in Windows 9x, and /dev type directories on Unix). The Products Folder is one of these types of Objects. I believe the rationale was as a centralized product management area (letting you see what Products where installed with the system), and as a development area for through-the-web products.
