Every project includes a Project panel. This acts as a storage area for all files used in the project. You can organize a project’s media and sequences using bins in the Project panel.

Within a single project file, you can edit individual segments as separate sequences, and then combine the segments into a finished program by nesting them in a longer sequence. Similarly, you can store multiple variations of a sequence in the same project.

Adobe Premiere Pro doesn’t store video, audio, or still image files in the project file—it stores only a reference to each of these files based on its filename and location at the time you imported it. If you later move, rename, or delete a source file, Adobe Premiere Pro can’t find it automatically the next time you open the project. In this case, Adobe Premiere Pro displays the Where Is The File dialog box.
