File storage allows you to bring in whole files/folders that are stored elsewhere on your computer so that you can access them from within Palace.
To do this, go to the relevant Diary from the Property list. Then click on FILE STORAGE.
This allows you to drag and drop files into this area. Files will be saved with the same file name.
To download after importing, click the BLUE arrow.
To delete, click the RED cross.
You don't need to save, you can just close out of that screen.
