Project Packer has an automatic system to Save & Restore your project settings.
These settings are located in a database with the name settings (settings.dbf, settings.dbt and settings.mdx), in directory Orontes - Project Packer, in your Documents directory.
Every time you click on the Build Archive button, the current settings will be saved in the settings database.
To restore the settings of one of your projects, simple use the add file(s) or add with wildcards buttons and select/enter the first line in the listbox from a previous project. When the entry is found, all the settings are restored in Project Packer.
