What does importing a file mean in video editing?

Importing a file in video editing refers to the process of bringing external media—such as video clips, audio files, or images—into an editing program. This allows the editor to access and utilize these files in their project workspace. By importing, files become part of the project, making it possible to cut, arrange, or modify them as needed to create the final edited video.

The other options do not accurately describe the act of importing. For instance, exporting involves saving a project in a different format or rendering it for delivery, while creating a backup refers to duplicating project files for safety, and manipulating file size pertains to adjusting the dimensions or bitrate of a video file rather than adding it to a project.
