I was recently working on a new Captivate project and needed to grab several assets that had been used in an older project. Some of the assets were audio files; others were images. I could have inserted each of the assets into the new project manually (I knew where the original assets were located on my server). I could have also opened the project containing the assets and copied/pasted assets from one project to another. While both of these techniques are fine, I found it easier and faster to utilize the Libraries of both projects. Simply put, I copied the assets I needed from the original project's library into my new project's Library. Here's how:
With the new project open, display the Library (Window menu). Then click the Open Library tool (located near the top of the Library).
When the Open dialog box appears, open the project that contains the Library you need. In the image below, I've positioned the two Libraries side-by-side. The Library at the left contains the assets I needed. The Library at the right is the empty Library in my new project.
Grabbing assets from one Library for use in another project at this point is as simple as selecting, dragging, and dropping. In the image below, I grabbed two files from the Audio folder of the original project and dragged them into the Library in my new project. And... done.
