Adobe Premiere Pro for Windows can open project files created with Adobe Premiere Pro or Adobe Premiere 6.x. You can open only one project at a time. To transfer the contents of one project into another, use the Import command.
Use the Auto Save command to automatically save copies of your projects in the Adobe Premiere Pro Auto-Save folder.
You may encounter missing files as you work on a project. You can continue working by substituting offline files as placeholders for the missing files. You can edit using offline files, but you must bring the originals back online before rendering your movie.
To bring a file back online after the project is open, use the Link Media command. You can continue working without having to close and reopen the project.
