I'm creating a web site for a photographer with Joomla using Phoca Gallery and in "Images - Multiple add". I would like to select a folder (principalFolder) which contains subfolders (folder1, folder2, ...) and I would like Phoca Gallery to create a category for principalFolder and subcategories for each folder1, folder2.... But when I want to select my principalFolder, the browser opens it instead of select; and when I transform my principalFolder in to principalFolder.zip I have the error message: "Invalid file extension: principalFolder.zip".
Can you help me ?
