In order to create a new multi-format object, the user should :
...
The first step of the new object creator is to select the main file of the object (see the image below). The user should select the “multi-format” option as the data source and indicate the directory on the local drive of the computer (by clicking the “Select a directory” button) which contains the subdirectories with objects in various formats (for the list of the object formats available by default, see the File Formats Available for Multi-Format Objects point. The directories for those formats should be named as follows:
- for the DjVu format – a directory labeled “DjVu”,
- for the PDF format – a directory labeled “PDF”,
- for the image gallery format – a the directory labeled “Gallery”,
- for the audio format – a directory labeled “Audio”,
- for the video format – a directory labeled “Video”,
- for the EPUB format – a directory labeled “EPUB”, and
- for the MOBI format – a directory labeled “MOBI”.
...
Next, the default format of the object should be indicated (in the “Default format” column). That format will be displayed when the website user does not indicate directly the format he or she wants to use (for example, after the object content icon has been clicked).
By default, the Editor Application detects the main file for every format automatically, but the main file for each format can be modified manually in the “Main file” column. The application identifies the main files for the formats in accordance with the following general rules:
- DjVu: The main file is a file named index*.djvu, a file named index*.htm, or a file named index*.html, gdzie * owhere * means any sequence of alphanumeric characters, the minus symbol „-“, or the underscore symbol „_“.
- PDF: The main file is the file in the directory. The file should have the “.pdf” extension.
- If the gallery has many images, the main file is the file generated automatically by the Editor Application (presentation.xml). If there is only one file in the directory, the main file is a graphics file.
- Audio: The main file is the file in the directory. The file should have the “.mp3” extension. It should be prepared in such a way that it will support so-called progressive download.
- Wideo: The main file is the file in the directory. The file should have the “.mp4” extension. It should be prepared in such a way that it will support so-called progressive download.
- EPUB: The main file is the file in the directory. The file should have the “.epub” extension.
- MOBI: The main file is the file in the directory. The file should have the “.mobi” extension.
invoke the New Object Wizard and select the "Multiformat Object" data source in the first step. See the Creating a New Object chapter for more details.

Having selected the directory, the user should indicate the default format for the files of the multi-format object and choose the main file for each format, if the main file is to be different than the automatically identified one.
Next, the files of the multi-format object should be sent to the dLibra server by clicking the “Start” button.
Finally, the object has to be republished by selecting the “Published” option in the “Edition” tab, in the “Publishing” section.
