What is a Photo DVD Maker (.pdm) project?

The .pdm file is the project document of the photo slideshow you create with Photo DVD Maker.

The .pdm file keeps a record of all the information about the photo slideshow you create and modify, such as project name, album names, names and locations of source images, effects used, theme chosen, etc. All settings are written in the .pdm file.

However, the project file does not include the photos or music used for the slideshow. If you move the source images or audio files, or rename these files, the next time you open the .pdm project, you will find some images or music missed, because the program can’t load them from previous locations.

Do keep all source files (images and music) in original locations if you’d like to edit the project latter and don’t like to load them again.

Remember that exported slideshow video can’t be edited any more. So you must save a project file for your photo slideshow, in case you need to made changes latter.
