SAVE/EXPORT FILE FORMATS
This is the native project format of FL Studio. It retains all data that belongs to your project, but note that this does not include any wave samples (unless there is an Edison Wave Editor loaded with an audio in the project), DrumSynth and SimSynth presets that are included in the project. To export package that includes samples used in the project, save to a Zipped Project Package instead.
NOTE: Demo plugins are saved with the project BUT next time you open the project they will be replaced with placeholders. You will receive a warning about this when you try to save to .flp/.zip that contains a demo plugin. Sad solution - Replace demo plugins with non-demo ones prior to saving. Happy solution - Continue with the save, then buy the plugin, next time you open the project the plugin/s will re-load and be out of demo mode :)
