When you start to make slideshows with Photo Slideshow Maker, you create a Flash Slideshow project.
The project file has a .psm file extension. There is another project file with the extension of .info. These two files does not store the photos nor music you used for the slideshow, but the name and location of these photos and music, what effects you applied to the slideshow, and which flash template you choose, etc.
If you do not save a copy of the flash slideshow as a project file, you will not be able to edit once you close the project.
And, if you move the photos or music after creating the slideshow project, the program will not be able to load the photos nor music again.
To save a flash slideshow project, click the File menu, and then click Save. Or you can press the keyboard shortcut Ctrl + S to save the project.
To restore a flash slideshow project, click the File menu, and then click Open Flash Slide Show Project. Or you can use the keyboard shortcut Ctrl + O to open a saved flash slideshow project.
