on disk remain untouched.

Exchanging Media in a Project
You can overwrite an image layer with media from a different file in the File Browser or
Library. This process, called exchanging media, replaces the layer’s original source media
link with a new source media link. When you exchange a layer’s source media, the layer
retains its Property Inspector parameter values (including the Position, Scale, and Opacity,
and Blend Mode), as well as applied filters, behaviors, masks, or keyframes.
The exchange operation allows you to replace layers in your project even after you’ve
modified and animated them. If you’re unhappy with an element of your composition,
exchange it with a new one.
Important: You can only exchange layers that are linked to media files on disk. You cannot
exchange Motion-generated objects such as particle systems, generators, shapes, or text
objects.
To exchange media in a layer
1 Drag a media file from the File Browser onto a layer in the Layers list.
2 When a curved pointer appears, release the mouse button.
