If you import multiple files, you have to define a main (=start) file of the project. .
The start file is the file that is opened first from the All-In-One Player. It can be a .SWF (flash) , .PDF (Adobe PDF), EXE (executable) or video / audio file., which loads other files. Select the file and press the button Define as starting file
All your files are imported in one single data file and stored in an encrypted format (AIPPROJECT). If you make changes on the original files, you have to reimport the files.
