16 Part I Organizing Footage and Preparing to Edit
Bins are unique to project files. Although they behave similarly to folders on your hard
disk, bins are not actually connected to folders on your hard disk in any way. Changes
you make to the contents of a bin, such as deleting, moving, and renaming clips or
renaming the bin itself, have no effect on the original files or folders on disk where the
media files are stored. If you delete a clip from a bin, its associated media file is not
deleted from your scratch disk. Likewise, creating a new bin does not create a new
folder on your disk.
Creating New Bins
You can create separate bins for different stages of your project or for different types of
footage. For example, you can create bins for each location the footage was shot in, or
you can create bins to separate your audio, video, and still image clips. You can
organize bins hierarchically and open them in their own windows. You can even put
bins inside other bins.
To add a new bin to a project:
1 In the Browser, click the project tab where you want to add a bin.
2 Do one of the following:
 Choose File > New > Bin.
 Control-click in the Name column, then choose New Bin from the shortcut menu.
 Press Command-B.
3 Enter a name for the new bin.
You can also create bins by dragging a folder from your hard disk to the Browser.
Enter a name for the bin.
