The Project Packer ppa or exe file creates a VIRTUAL ZONE in the memory of the computer, where the RUN file and all other files in the database are copied. After copying the files, the RUN file is started.
The VIRTUAL ZONE simulates a disk. If the EXE file opens another file or starts another application, the file is first searched in the VIRTUAL ZONE. If the file is not found in the VIRTUAL ZONE, it is searched in the real file system. This technique ensures, that an application runs without modification. An access to the VIRTUAL ZONE from outside is not possible - all files are completely protected during runtime.
